Emergence of lobed wakes during the sedimentation of spheres in viscoelastic fluids

The motion of rigid particles in complex fluids is ubiquitous in natural and industrial processes. The most popular toy model for understanding the physics of such systems is the settling of a solid sphere in a viscoelastic fluid. There is general agreement that an elastic wake develops downstream of the sphere, causing the breakage of fore-and-aft symmetry, while the flow remains axisymmetric, independent of fluid viscoelasticity and flow conditions. Using a continuum mechanics model, we reveal that axisymmetry holds only for weak viscoelastic flows. Beyond a critical value of the settling velocity, steady, non-axisymmetric disturbances develop peripherally of the rear pole of the sphere, giving rise to a four-lobed fingering instability. The transition from axisymmetric to non-axisymmetric flow fields is characterized by a regular bifurcation and depends solely on the interplay between shear and extensional properties of the viscoelastic fluid under different flow regimes. At higher settling velocities, each lobe tip is split into two new lobes, resembling fractal fingering in interfacial flows. For the first time, we capture an elastic fingering instability under steady-state conditions, and provide the missing information for understanding and predicting such instabilities in the response of viscoelastic fluids and soft media.

Prediction of steady hydrodynamic performance of pump jet propulsion based on free wake vortex model

Due to mutual interference between various components, the transitional motion of fluid particles in the flow field of pump jet propulsion becomes more complex and variable. Additionally, the vortex structure at the wake can undergo severe contraction and deformation. To further improve the accuracy of predicting the hydrodynamic performance of pump jet propulsion, this paper proposes a time-varying, space-varying, and induced velocity-varying free wake numerical calculation model based on potential flow theory. A set of hydrodynamic performance prediction methods that consider the interference of the free wake model is also established. Furthermore, a velocity smoothing model based on time reversal is constructed based on the distribution pattern of numerical singularity points during the induced velocity calculation process, which enhances the robustness of the calculation program. By comparing and analyzing the numerical calculation results with experimental results, including pressure, circulation distribution, and hydrodynamic performance, the accuracy of the free wake model proposed in this paper is verified. The results also demonstrate that the free wake model proposed in this paper can effectively improve the prediction accuracy of the hydrodynamic performance of the pump jet propulsion.

Unsteady electroosmotic flow of Carreau–Newtonian fluids through a cylindrical tube

The present study aims to investigate the fully developed electroosmotic flow of Carreau–Newtonian fluids within a circular tube, considering two different boundary conditions of zeta potential. The unsteady behavior of Carreau–Newtonian fluids, is attributed to the pulsatile pressure-driven flow. Studying two distinct formulations, slip and no-slip zeta potentials, illustrates the relative movement of fluid particles and the charged surface. The proposed study’s framework is divided into two regions: a central region containing a non-Newtonian Carreau fluid exhibiting both shear-thinning and thickening behavior, and a peripheral region containing a Newtonian fluid with the effect of an electrical double layer at the solid wall of the cylindrical tube. The Poisson–Boltzmann equation under the assumption of Debye–Hückel approximation governs the potential distribution due to the electric double layer, facilitating the examination of electroosmotic flow through tube. Obtaining analytical solutions for the momentum equations in both regions becomes challenging due to the inclusion of pulsatile pressure-driven flow and a non-Newtonian Carreau fluid. Asymptotic series expansions are employed, utilizing small parameters such as the Weissenberg number (We≪1) and a pulsatile Reynolds number (α≪1), to derive velocity expressions for both regions. Wall shear stress fluctuations, as indicated by time-averaged wall shear stress and oscillatory shear index are assessed to gauge the temporal variation of wall shear stress from the dominant blood flow direction. By utilizing potential and hydrodynamic variables, an asymptotic formulation for the streaming potential is developed to ascertain the asymptotic expression of electrokinetic energy conversion efficiency and scrutinize the impacts of pertinent physical parameters on it. The proposed study prominently shows that the Debye–Hückel parameter, Weissenberg number, pulsatile Reynolds number, and time-dependent pressure gradient significantly influence the fluid velocity, flow rate, and flow resistance. The notable determination of the present study is that the velocity amplitude and electrokinetic energy conversion efficiency are enlarged in the slip-dependent case relative to the no-slip zeta potential. It is noteworthy that as inertial forces become more prominent compared to viscous forces, both time-average wall shear stress and oscillatory shear index experience a slight decrease, although the reduction in oscillatory shear index is minimal owing to the absence of obstruction within the tube wall. The NDSolve numerical scheme in Mathematica software is employed to calculate numerical solutions for the governing equations, which are subsequently verified against results obtained through asymptotic analysis. The findings of this study are expected to deepen our understanding of unsteady electroosmotic flows of Carreau fluid and contribute to the design and development of advanced microfluidic devices with enhanced performance for various applications.

Viscous heating and thermal gyration of magneto-micropolar fluid particles through an isothermal porous fixed channel with internal non-uniform heat generation: An analytical investigation

The experimental and theoretical analysis of viscous dissipation and heat generation/absorption management is crucial in engineering, medical, biological, and exploration activities. This study investigates the analytical solution of viscous heating and thermal gyration of magneto-micropolar fluid particles across a resistive medium with internal non-uniform heat generation/absorption. The formulated partial differential equations were appropriately converted into coupled ordinary differential equations employing similarity variables along with the boundary conditions. The simulation of the resultant equations is carried out using the collocating weighted residual scheme, and the result is validated using the shooting technique via the Runge-Kutta method of order four, Adomian decomposition technique, variational iteration scheme, differential transform method, and quasi-linearization technique as the control methods. Tabular and graphical representations are provided to illustrate the flow characteristics. Taking from the results, the existence of a magnetic field retards the gyration of the fluid particle motion. The spin gradient and vortex viscosity terms reveal the reverse occurrence of micro-rotation distribution, and it is seen that the porosity term suppresses the velocity field. Furthermore, it is observed that the parameters that enhance internal heat generation decrease the viscosity of the fluid in the region. Hence, these findings will assist scientists and engineers to effectively manage heat generation/absorption in industries where effective heat transfer activities are crucial to achieving ideal performance and reducing energy waste.

Unsteady flow of bubble liquid in hydraulic systems of aircraft and helicopters

The subject of this work is the phenomenon of a water hammer in a liquid that contains a small volume of gas bubbles. Historically, this phenomenon began to be studied as the dynamics of gas bubbles (Rayleigh-Pleset equation). Today, thanks to progress in computer technology, this phenomenon is studied at the level of bubble deformation during hydraulic shock. Another approach is to consider the dynamics of a multiphase (two-phase) medium in the form of a bubbly liquid. After several assumptions, the main one being a relatively small gas content in the liquid, the model consists of two differential equations with respect to the shock wave propagation speed and the resulting pressure perturbations. The specified system of equations differs from the corresponding classical water hammer equations: they consider the convection of the velocity field. In addition, the friction of the liquid against the wall according to the Weisbach-Darcy model is considered. Because of the small content of gas bubbles, the Weissbach-Darcy friction is approximated in the same way as in a homogeneous liquid, i.e., in a certain sense, greater than the real friction. Maybe that is why more or less physical results are obtained only for small values of the dimensionless parameter responsible for the friction of the liquid against the wall. It concerns the non-contradiction of the assumptions and the results obtained on their basis. Thus, in the front region of the shock pulse, where the pressure increases, the radial velocity of the bubbles is negative; however, for relatively large values of the friction parameter, the maximum pressure disturbance moves from the center of the shock pulse. This contradicts the assumption about compression: after passing the maximum pressure, gas bubbles expand due to a decrease in pressure. The graphical dependence obtained in this study are compared with the results related to a homogeneous liquid. They agree, but the shock pulse in a bubbly liquid is not as concentrated in space as that in a homogeneous liquid. Its length is 10-12 times greater than the corresponding value in a homogeneous liquid. Research methods are purely theoretical. The well-known bubble liquid model is used as a single-speed model continuum. Differential equations are solved analytically, approximately (series expansion), and numerically. In addition, the original approach of obtaining an analytical solution of an autonomous system is used-finding the function of pressure disturbances from the velocity of propagation of the shock pulse (and vice versa). Conclusions. A simple one-dimensional hydraulic model of shock wave (impulse) propagation in a bubbly liquid is proposed. In contrast to classical ideas (solutions) about a water hammer, which consists of two waves of opposite directions of propagation, a shock pulse is a region of pressure disturbances in which the speed of motion of fluid particles is also variable – from the maximum value to almost zero.

Modeling sound speed profile based on ocean normal mode

IntroductionStatistical methods such as empirical orthogonal functions (EOFs) are often used to model the sound speed profile (SSP). However, their statistical nature often leads to the sample dependence and physical fuzziness.MethodThis study proposes a technique for modeling the SSP from the perspective of ocean dynamics. It employs the ocean normal mode, which is the mode of fluid particles motion, to deduce perturbations in the SSP, which is called the ocean mode basis (OMB).ResultThe results of SSP reconstruction of in-situ samples showed that a few leading orders of the OMB can provide a compact representation of the SSP. Oscillations of the contours and gradient of the sound speed in thermocline were analyzed by using the first two orders of the projection coefficients of the relationship between the OMB and the baroclinic mode. As a physical model, this technique can also be used to characterize the dynamics of internal solitary waves. Furthermore, the OMB derived from archival date was used for SSP inversion. The results showed that the OMB can reconstruct SSP of a reasonable resolution without requiring in-situ samples.DiscussionCompared with statistical models, the OMB can better explain the ocean dynamics underlying variations in the SSP while requiring fewer samples.

Slip topology of steady flows around a critical point: Taking the linear velocity field as an example

The flow of viscous fluids is considered as the aggregation of the motion of fluid particles when the fluid is conceived to be made up by an infinite number of particles. As an alternative of this conventional model, fluid motion could be understood as the slip of fluid layers with a molecular scale over each other, where the slip structures of fluid and their associated small-scale motion are characterized by an axial-vector-valued differential 1-form, called the vortex field. In this paper, in the case of steady flows we define the swirling degree of the velocity field at a point, and further the swirl field of the steady flow, to study the slip topology of fluid or the local streamline pattern around the critical point. The linear velocity field in the right real Schur form is used to carry out detailed analyses around the isolated critical point. Theoretical deduction and numerical test unveil the connection between the swirling degree and the swirl field, greatly make clear the topological property of slip structures of fluid in steady flows, especially in three-dimensional space.

Визуализация течений вязкой несжимаемой жидкости, соответствующих точным решениям уравнений Навье-Стокса

The work visualizes flows corresponding to the exact solutions of the system of hydrodynamic equations previously published by the authors, consisting of the vector Navier-Stokes equation and the law of conservation of mass for an incompressible fluid. This work uses the MathGL library for the C/C++ language and ParaView for scientific visualization of the results of numerical and analytical calculations. Without the use of such means, it would be impossible to see that the fluid flow is stratified into invariant subregions, and the trajectories of motion of fluid particles are wound on torus-shaped surfaces. Most of the scientific works on the study of hydrodynamic equations cover the results of calculations and do not address the questions of the existence of exact analytical solutions. At the same time, these calculations are performed with a specially selected set of fitting parameters unique to the equipment used and the computer software used. Questions about trust in the results of such calculations, their verification with exact solutions and the creation of a bank of test examples of applied problems in order to certify the applicability of the calculation results in practice become relevant.

Improvement of the two-fluid momentum equation for turbulent bubbly flows

A two-fluid model is widely employed to predict gas–liquid two-phase flows. Conventional two-fluid equations, derived by assuming that all phases are interpenetrating continua, occasionally yield impractical results. For example, the bubble velocity is predicted to be higher than the water velocity for a horizontal fully developed bubbly flow. One solution for this irrational result is two-fluid momentum equations based on the motion of fluid particles. This study revisits the particle-motion-based two-fluid equations. Previously, it was validated only with respect to the difference between the bubble and liquid velocities. Recently, we observed an erroneous prediction of the void fraction distribution by the existing particle-motion-based momentum equations. This study, through rigorous analysis, discovered that this error could be resolved by neglecting the turbulent kinetic energy term in the particle-motion-based equation for the gas phase. Subsequently, the revised momentum equations were applied to the vertical and horizontal air–water bubbly flows. The conventional and revised momentum equations produced similar results for upward bubbly flows because the relative velocity between the bubble and water phases was mainly governed by buoyancy. For horizontal bubbly flows, the revised momentum equations led to a downward shift in the liquid velocity distributions, which was attributed to the modified momentum diffusion term. At a higher modification factor of turbulent dispersion, the velocity distributions exhibited an upward shift. We conclude that the optimization of physical models should be based on the revised two-fluid momentum equations.

A GPU-based hydrodynamic simulator with boid interactions

We present a hydrodynamic simulation system using the GPU compute shaders of DirectX for simulating virtual agent behaviors and navigation inside a smoothed particle hydrodynamical (SPH) fluid environment with real-time water mesh surface reconstruction. The current SPH literature includes interactions between SPH and heterogeneous meshes but seldom involves interactions between SPH and virtual boid agents. The contribution of the system lies in the combination of the parallel smoothed particle hydrodynamics model with the distributed boid model of virtual agents to enable agents to interact with fluids. The agents based on the boid algorithm influence the motion of SPH fluid particles, and the forces from the SPH algorithm affect the movement of the boids. To enable realistic fluid rendering and simulation in a particle-based system, it is essential to construct a mesh from the particle attributes. Our system also contributes to the surface reconstruction aspect of the pipeline, in which we performed a set of experiments with the parallel marching cubes algorithm per frame for constructing the mesh from the fluid particles in a real-time compute and memory-intensive application, producing a wide range of triangle configurations. We also demonstrate that our system is versatile enough for reinforced robotic agents instead of boid agents to interact with the fluid environment for underwater navigation and remote control engineering purposes.

Non-Boussinesq effect on the internal solitary wave propagation under a Lagrangian-like description for various pycnocline thickness conditions

The Dubreil–Jacotin–Long (DJL) equation is an exact model for the steady propagation of internal solitary waves (ISWs) under Boussinesq approximation. The aim of this study is to discuss the non-Boussinesq effect on ISWs initialized by DJL equation for various pycnocline thickness conditions. The simulated results show that the non-Boussinesq effect can indeed lead to instability of DJL equation, and the pycnocline thickness will affect the amplitude of re-stable ISWs and the separation process of tail waves. Moreover, in order to extract features of the non-Boussinesq instability and the location of the tail wave separation, we propose an effective analytical approach for the quasi-traveling wave problem inspired by the definition of classical Lagrangian coherent structure (LCS). The improved finite-time Lyapunov exponent with a moving window (FTLEmw) is a Lagrangian-like description with considering the prior information of physical phenomenon. For a steady ISW propagation in the Boussinesq system, the repelling and attracting FTLEmv fields are symmetrical and the field ridge behaves as a continuous spiral topology, which suggests that particles on different streamlines in the flow structure have different rotation periods, while the streamlines are not actually completely closed due to the forward propagation of the wave. During the main unstable stage of non-Boussinesq effect, the topology of separated tail wave which is disconnected from the ISW main part can be clearly distinguished. The tail wave separation locations identified by the improved FTLEmv field and the classical FTLE field are not the same, which illustrates the difference between the two perspectives of flow structure change and fluid particle motion. In addition, the leading edge, trailing edge and main part of ISWs will gradually be divided into three-part FTLEmv topologies in the thicker pycnocline conditions.

Nearly Toroidal, Periodic and Quasi-periodic Motions of Fluid Particles Driven by the Gavrilov Solutions of the Euler Equations

We consider the smooth, compactly supported solutions of the steady 3D Euler equations of incompressible fluids constructed by Gavrilov (Geom Funct Anal (GAFA) 29(1):190–197, 2019), and we study the corresponding fluid particle dynamics. This is an ode analysis, which contributes to the description of Gavrilov’s vector field.

Controlling the Motion of Interfaces in Capillary Channels with Non-uniform Surface Wettability

The use of self-driven flows in microfluidic devices attracts many researchers as the external flow-driving mechanism is diminished or eliminated. One of the mechanisms providing such motions is generating a pressure difference across interfaces as in the case of the motion in capillary tubes. The capillarity, namely, the pressure difference across the interface due to its curvature drives the motion. This pressure depends on the interaction with the capillary walls and is controlled if one varies the surface energy of the walls. In this study, we search for the effects of surface energy on the motion of interfaces in capillary-driven flow. To this end, we model the motion of fluid particles in a capillary channel and integrate the governing equations using the binary lattice Boltzmann method for the two-phase flow. We, first, validate our solver for canonical static and dynamic problems. We, then, discuss two main contributions; we show how to deviate the interface speed from the ones moving in channels with uniform wall energies and discuss the conditions under which such an interface stagnates (like a passive valve in a channel). Tuning the wettability of the channel walls, we provide a simple condition for stopping the interface: the summation of the equilibrium contact angles interface make with the channel walls at the bottom and top wall need to satisfy $\theta_{eq}^{top}+\theta_{eq}^{bot} \geq \pi$. Configurations and wetting properties of different wettability regions play major roles together

Utilization of Cattaneo–Christov theory to study heat transfer in Powell–Eyring fluid of hyperbolic heat equation

In this article, the two-dimensional, steady flow, and incompressible flow of Powell–Eyring fluid (non-Newtonian fluid) is considered toward a stretching surface. Applications of this emerging challenge include heating meals, grilling, baking, roasting, treating wounds, inflammation, and injuries with thermotherapy and cryotherapy, as well as steam turbines, industrial operations, casting, smelting, cooling aviation engines, and other things. Motion of particles is induced using variable wall velocity involving constant magnetic field. The characteristics of Lorentz force (magnetic field) and stagnation point flow are analyzed while direction of Lorentz is implemented toward y-direction of a bidirectional stretching surface under consideration of low magnetic Reynolds parameter. The phenomena regarding transfer of thermal energy have been addressed subject to thermal radiation, non-Fourier’s law and Joule heating. The PD-equations (partial differential equations) associated with heat transfer and flow are re-framed in forms of OD-equations (ordinary differential equations) using similarity variables. The influences based on various parameters against variation of motion and temperature field are analyzed in tables and graphical forms. The features of divergent velocity and temperature gradient are tabulated in Table 1. It is noted that temperature field is decreased against argument values of the Prandtl number whereas the same impact is noticed in thickness regarding thermal layers. The fluid parameter brings maximum acceleration into motion of fluid particles but the opposite trend is noticed in motion of fluid particles versus enhancement of Ratio of expansion rates number and Powell–Eyring fluid parameter.

Optimizing particle translation and self-rotation by adjusting gravity-driven hydrocyclone inclination angle for separation and activation of granular sludge

Hydrocyclone was experimentally confirmed important for the granulation, separation, and activation of granular sludge. However, almost all the existing hydrocyclones are pressure-driven, requiring an intake pump to transport materials. Recent experiments revealed granular sludge breakdown occurred more in intake pumps than hydrocyclones. Therefore, we proposed the gravity-driven hydrocyclone operating like a waterfall to separate and activate the granular sludge, with the benefit of avoiding granular sludge crushing. CFD simulations were carried out to study the effects of inclination angle on the fluid flow and particle motion, and separation performance. Results show that the proposed gravity-driven hydrocyclone without intake pump can successfully activate and separate the 0.5-mm simulated granular sludge. Unlike a widely used pressure-driven hydrocyclone, the new hydrocyclone gives the separation efficiency and split ratio positively correlated with the inclination angle. Generally, the inclination angle does not significantly affect particle translation, particle self-rotation, and particle revolution. The maximum angular and linear velocities of particle self-rotation are mainly obtained in the cylindrical section, especially its upper part. The shear stress of the fluid micro cluster obtains its maximum near the wall, and the maximum wall shear stress is only 252 Pa.

Improving the thermal efficiency of parabolic trough collector equipped with combined turbulator containing two-phase magnetic hybrid nanofluid

A parabolic trough collector (PTC) is a beneficial device for collecting heat from the sun. Increasing the efficiency of these devices in recent years has attracted the attention of researchers to a significant extent. The present study has been carried out to increase the thermal efficiency in the PTC by using a new geometric form of compound turbulator and magnetic hybrid nanofluid. In this study, MWCNT-Fe3O4-Cu/Water magnetic hybrid nanofluid is prepared using a two-step method. Then its thermophysical properties are used as a working fluid in the present study. The absorber tube of the studied PTC is equipped with three different geometric shapes of the compound turbulator (Case A, B, and C). Case A and B geometric shapes differ in their vertical or horizontal position. Therefore, a circular coil is wrapped around the compound turbulator in Case C. Magnetic hybrid nanofluid is simulated in the Reynolds range of 18,000 to 42,000 and volume fraction 1.25 and 2.25% of nanoparticles considering the two-step method. The results show that using a magnetic hybrid nanofluid with three MWCNT, Fe3O4, and Cu nanoparticles in the PTC always causes the heat transfer rate to be higher than the water. Adding the compound turbulator has caused, unlike the laminar flow in which the movement of fluid particles is in the form of layers, the fluid particles in the direction perpendicular to the movement path are also mixed and create a random movement. The analyzed results of the thermal–hydraulic performance evaluation criteria describe that in this study, using the compound turbulator in the absorber tube of the PTC always has a favorable role. Finally, the maximum exergy efficiency and energy efficiency are related to the absorber tube equipped with a combination of a compound turbulator and circular coil.

CONVEYOR-TYPE SMALL HYDROPOWER PLANT FOR SHALLOW RIVER WATERS

This paper deals with the development of a small conveyor-type hydropower plant intended for operation in shallow river waters without construction of a dam. The proposed design offers a closed-shaped flattened conveyor equipped with flat-shaped blades. The conveyor is oriented perpendicular to the fluid flow. Several identical flat blades interacting with fluid flow are mounted on conveyor belt and move together with the belt in one straight line direction. Then after turning in the reversing mechanism, blades move in the opposite direction. The conveyor system has a built-in energy generator which drive shaft is connected with one of the reversing ends of the plant. Conveyor belt system dynamics analysis is performed on the base of equivalent model with one degree of freedom. The interaction of a moving conveyor flat blade in translation motion with fluid flow is studied by computer simulation with program Mathcad using a superposition principle. In accordance with this approach, a fast-chaotic motion of fluid particles (Brownian motion) is separated from the slow-directed flow motion, with the given average velocity. Optimization of system parameters (blade orientation angle to fluid flow, interaction constants of the braking generator) is performed, using a generated power as criterion. Simulation results confirm the serviceability and operational efficiency of the proposed hydropower plant in shallow river waters.

Simulation Analysis of the Motion of Superparamagnetic Particles in Liquid-Phase Fluid under a Magnetic Field

Based on the magnetic response of magnetic particles, the targeting of particles to a target area under the modulation of an external magnetic field has been used in many applications. An accurate kinematic model is helpful to achieve accurate targeting of magnetic particles and to investigate the factors influencing the motion of the particles. In the present paper, a segmental magnetization model was proposed based on the real magnetization process of superparamagnetic particles to calculate the magnetic force, and this was compared with a traditional magnetization model. The effects of magnetic field strength and particle diameter on the trajectory of magnetic particles in fluids under a magnetic field were further analyzed using a finite element analysis software. The simulation results show that changing the particle size only affected the velocity of the particles and did not affect the trajectory. When magnetic field strength changed, magnetic particles showed different trajectories. Notably, when the magnetic field force in the Y direction was too large, meaning the gravity could be neglected, the trajectory of the particles no longer changed when the magnetic field strength was varied.

Homogeneous–heterogeneous reactions for Maxwell nanofluid flow over an elongating cylindrical pipe via finite element method

AbstractHomogeneous–heterogeneous chemical reactions in simultaneous heat and mass transport for Maxwell fluid subjected to thermophoresis and Brownian motion are modeled and governing mathematical models are simplified using approximations proposed models are simplified using approximations proposed by Ludwing Prandtl. The simplified governing mathematical models under Buongiorno's theory are numerically solved via finite element method (FEM). The convergence and mesh free solution are solved for parametric study. The momentum relaxation phenomenon is the characteristic of liquid to restore its equilibrium state. Therefore, a remarkable reduction in the motion of fluid particles against an increase in Deborah number is noticed. A rise in temperature distribution is noticed when Brownian motion parameter is enhanced. The flow is decelerated as the curvature of the cylinder increases. As a consequence, the viscous region shrinks and its thickness becomes smaller. Hence, it is concluded that flow over flat surface has wider boundary layer region than the boundary layer region associated with flow over the cylindrical surface. The wall shear stress for the flow over a cylindrical object is higher than that for the flow over a flat surface. The wall heat and mass fluxes have an increasing tendency when the curvature parameter is increased. Wall heat flux and wall mass flux have opposite behavior due to rise in thermophorsis and Brownian motion effects.

Computational study on magnetohydrodynamics heat and mass transport in polymeric liquid using micropolar theory of fluids

Theory of Eringen for polymer fluid, called micropolar fluid, has revealed that if micro-solid structures or nano-sized solid bodies are immersed in polymers, then vortex and spin gradient effects become significant and the flow of such polymers cannot be modeled by the usual Newtonian rheological model or non-Newtonian model which do not capture vortex and spin gradient effects due to couple stress exerted by nano- or microstructures. Thus this manuscript uses Eringen's theory and generalized Fourier law for modeling of flows and related mechanisms like heat and mass transfer. Models are solved numerically and simulations are visualized. The different samples of parametric values are chosen during numerical experiments and outcomes are examined. The mass flux has shown an increasing behavior versus vortex motion of fluid particles due to raise in convective transport of mass of solute. It is also found that mass flux in hybrid nanopolymers is less than that in mono nanopolymers. Magnetic field intensity is directly proportional to the mass flux and therefore, an increase in mass flux due to an increase in Hartmann number is observed. Solutal relaxation time has shown an increasing behavior on the mass flux.
