Non-similar investigation of magnetized boundary layer flow of nanofluid with the effects of Joule heating, viscous dissipation and heat source/sink

The main objective of this numerical study is to investigate the steady, incompressible and two-dimensional magnetohydrodynamic convection flow of a nanofluid across a stretched sheet with the influence of viscous dissipation, Joule heating, and slip condition. Also, the effects of convective boundary condition, mass flux and heat source are considered. The nanofluid under consideration is a combination of water and copper nanoparticles. In this analysis, appropriate non-similar transmutations are applied to transform partial differential equations (PDEs) into dimensionless PDEs. The dimensionless PDEs are converted into ordinary differential equations (ODEs) using the local non-similarity method. ODEs are solved through the use of well-known method (MATLAB-based bvp4c). The different results of velocity profile and temperature profile are conferred through graphs for several dimensionless parameters including Hartmann number, slip parameter, porosity parameter, Biot number and Eckert number. Physical quantities like Nusselt number and surface drag force are also estimated in tabular form. From the obtained results, it is noted that enhancing the values of volume fraction, slip parameter cause an increment in the values of skin friction coefficient while enhancing the values of Hartman number, porosity parameter causes a reduction in the values of skin friction coefficient. Also, by increasing the values of volume fraction, slip parameter, Eckert number causes a reduction in the values of local Nusselt number while the values of Nusselt number enhances by increasing the values of Hartman number, porosity parameter and heat source parameter.

Modelling and Optimization of Continual Laser Joining Processes for Silicon Aluminum Alloy in Microwave Devices

Due to its higher energy and smaller heating area, laser joining technology is widely used in aluminum alloy welding and other industrial fields, which meets the solder sealing requirements for electronic packaging. According to experiments, cracks were prone to occur at the corners and spot-welding positions near the weld. In this paper, the depth and width of the melt pool were measured experimentally, and the results were used to calibrate and validate the heat source model. An empirical relationship between heat source parameters and melt pool morphology is presented. The heat source model of laser deep penetration welding was established under the same experimental conditions. And the results were in agreement with the experimental results. The finite element method was used to numerically simulate the welding process of a 50%SiAl shell and a 27%SiAl cover plate. The effects of different spot-welding sequences and numbers on the residual stress and cracking possibility of laser welded samples were analyzed. The results show that under sequential spot-welding, when the amount of spot-welding is increased, the stress peak value decreases. Compared with sequential spot welding and side-by-side spot welding, the spot-welding sequence of diagonal points first, and then side-by-side spot welding, can effectively reduce the residual stress. This research enables us to provide some guidelines in terms of studying the reliability issues of microwave devices.

Joule heating effect on the MHD flow of tangent hyperbolic mixed nanofluid embedded with MgO and CuO nanoparticles

The present article emphasises on the study of the two-dimensional, steady, electrically conducting tangent hyperbolic mixed nanofluid flow across a linear/nonlinear elongating sheet with Joule heating and uneven heat source effect. The mixed nanoliquid is the amalgamation of oxides of Magnesium and Copper nanomaterial suspension in the methanol liquid. The governing yielded equations are resolved by adopting the bvp5c Matlab tool. The novelty of this research is to determine the enhanced energy transmission between linear and nonlinear extending sheet instances. The flow and temperature profiles for various constraints are graphed; furthermore, the wall friction and energy transmission rates are demonstrated via numeric values. The energy transmission rate in the nonlinear extending case is more substantial than the linear case in the nanoparticle volume factor. Also, uneven heat source and Joule heating parameters effectively amplify the thermal curves for both criteria.

On the non-Newtonian blood flow in the elliptical multi-stenosed inclined artery: Analytical approach

The analysis of blood flow in the stenotic artery is imperative as the existence and progression of stenosis effectively disturbs the blood flow in the artery, which may cause vascular disease. In this study, we considered the linearized Phan-Thien–Tanner (PTT) fluid model to study the non-Newtonian nature of blood flow in the stenosed artery inclined at an angle [Formula: see text]. The artery is considered to have multiple stenoses and a cross-section of elliptical shape. The PTT model is appropriate for this analysis as viscoelastic properties and shear-thinning characteristics characterize it. The elliptical cross-section of the artery raises the nonlinearity of the mathematical model and makes it effortful to solve the equations analytically. The mathematical equations of the model are processed to non-dimensional form under the assumptions of mild stenosis, which help us to get the exact solutions of the equations in the elliptical domain. The analytically acquired solutions are investigated in detail by their graphical interpretation. It is analyzed that progressive height of stenosis generates the more significant disorder in the narrowed part of the channel as the velocity reverses its behavior in that region. The advancing values of the Weissenberg number, Grashof number and extensional and heat source parameters cause to lessen the axial velocity and slow the fluid flow. The rising Grashof number has nearly no impact on the velocity in the center of the channel. The wall shear stress aggrandizes with the growth of stenosis height, and its behavior for other physical constraints is similar to the flow velocity. It also has a practical enhancement in the stenotic region of the conduit. It is observed that fluid velocity and wall shear stress have larger values for zero angles of inclination than the inclination angle of [Formula: see text]. The streamlined examination indicates the generation of the vortices in the stenotic part of the artery. Moreover, the flow velocity and wall shear stress have lower values for the nonuniform shape than for the uniform form of stenosis.

Entropy generation in unsteady stagnation flow through porous media in the presence of a high magnetic Reynolds number with a uniform heat source: renewable energy applications

The present model’s major focus is on entropy production and Newtonian, incompressible two-dimensional temperature-dependent stagnation point with uniform heat source factors in a porous channel. Furthermore, the induced magnetic field (IMF) is employed in this flow analysis, which is created by the movement of electrically conducting fluid. Entropy generation (EG) is an important aspect of any heat transfer development since it helps to reduce the irreversibility factor in a system. EG analysis has several applications in traditional industrial fields requiring fluid flows and heat transfer. As a result, the current study is concerned with the effects of EG. The relevant similar transformations are used to convert partial governing equations arising in the present model into ordinary differential equations (ODE). The bvp4c built-in code in MATLAB programming is then utilized to crack highly nonlinear equations. We arrive at numerical solutions by employing thebvp4c built-in code in MATLAB software. The results are plotted and discussed for various embedded parameters. It is discovered that because of low friction, the porosity parameter decreases the velocity and induces the magnetic boundary layer. Unsteady parameter and heat source parameters accelerate Bejan number, whereas the heat source and porosity constraints accelerate entropy analysis.

Analytical and numerical investigation of thermal distribution for hybrid nanofluid through an oblique artery with mild stenosis

In this study, the accuracy of three methods to simulate the thermal diffusivity profile in oblique stenosis artery with hybrid nanofluid and the influence of volume fraction and heat sources in the hybrid nanofluid, including Al2O3 and Cu, is studied. Comparing the analytical methods for reliable answers is important in the new studies. Also, the influence of volume fraction and heat source parameter S in temperature evolution is studied. Akbari–Ganji Method (AGM), Finite Element Method (FEM), and Runge–Kutta method are studied to calculate the stenosis artery's heat profile. The results are compared by reference value, AGM is the more accurate method than FEM and Runge–Kutta methods by less than 7 percent error, and FEM is more accurate than Runge–Kutta by less than 9 percent error. The maximum difference between the three methods happened near the wall of the vessel. 0.02, 0.03, and 0.05 is the volume fraction chosen for studying. Changing the volume fraction of nanoparticles is studied by enhancing the volume fraction of Nanoparticles and presenting the Al2O3, and Cu decreases the max temperature profile and increases the heat source by increasing the maximum heat temperature. Al2O3 has more influence on maximum heat temperature and decreases the temperature profile more.

Rheological behavior of magnetized ZnO – SAE50 nanolubricant over Riga plate: A theoretical study

[Formula: see text] nanolubricant is one of the most important nanolubricants having widespread uses in heat exchange systems and automobiles. It minimizes friction between moving parts and prevents them from corrosion and scrape, improves durability and performance of the system and also minimizes the consumption of fuel. This work investigates the rheological behavior of magnetized [Formula: see text] nanolubricant over moving/stationary Riga plate with viscous dissipation and nonlinear heat generation. The novel features of the current work are the use of [Formula: see text] nanolubricant as a flow fluid across a Riga plate and the application of the Patel model to boost the thermal conductivity of the nanolubricant. The governing system of equations is transformed to nonlinear ODEs and then treated analytically by using HAM. The augmentation in the velocity of nanolubricant [Formula: see text] is observed due to increasing values of Grashof number. The higher values of nonlinear thermal radiation and nonlinear heat generation parameters upsurge the temperature profile. The value of skin friction increases by increasing modified Hartman number and velocity slip parameter while reverse trend is observed by enhancing magnetic parameter. The radiation parameter, temperature dependent heat source parameter and solid volume fraction tend to augment Nusselt number at the Riga surface.

Three Dimensional Modelling of Magnetohydrodynamic Bio-Convective Casson Nanofluid Flow with Buoyancy Effects Over Exponential Stretching Sheet Along with Heat Source & Gyrotactic Micro-Organisms

In current analysis, influence of buoyancy forces in MHD bioconvective non-Newtonian nanofluids over three dimensional exponential sheet has been studied numerically. Additionally, impact of heat source parameter along with convective conditions has been incorporated. Moreover, nanofluid flow with gyrotactic microorganisms has been analyzed in presence of chemical reaction. Initially similarity variables are used for the conversion of partial differential equations into highly non-linear differential equations. Thusly, non-linear behavior of equations makes typical solutions which are not solved analytically. So, computational MATLAB software is used to calculate results and graphs by following shooting algorithm with Runge Kutta Fehlberg technique using ODE45 solver. Present modeling investigates the influence of crucial fluid parameters especially; magnetic M (0.1 ≤ M ≤ 0.9), Casson parameter β (0.09 ≤ β ≤ 0.13), permeability parameter Bθ, Brownian motion Nb (0.5 ≤ Nb ≤ 5.0), thermophoresis Nt (0.2 ≤ Nt ≤ 2.0), thermal Biot number Bt (0.3 ≤ Bt ≤ 0.7), heat generation parameter Q (0.1 ≤ Q ≤ 0.5), Prandtl number Pr (0.1 ≤ Pr ≤ 0.9), concentration Biot number Bc (0.1 ≤ Bc ≤ 0.9), Lewis number Le (1 ≤ Le ≤ 5), chemical reaction parameter Ch (0.1 ≤ Ch ≤ 0.9), bioconvective Lewis number Lb (0.1 ≤ Lb ≤ 2), Peclet number Pe (0.1 ≤ Pe ≤ 5), gyrotactic Biot number Bn (0.1 ≤ Bn ≤ 0.5), stretching ratio parameter c (0.1 ≤ c ≤ 0.3) and microorganism concentration difference parameter Ω (0.1 ≤ Ω ≤ 5.0). Final results are compared for Prandtl number and stretching ratio parameter along with residual errors. It is inferred that motile concentration declines for larger bioconvective Lewis number whereas rises for motile gyrotactic microorganism Biot number.

Volumetric chemical reactive Casson fluid flow over a nonlinear extended surface

The thermophysical features of viscoelastic fluid flow caused by a nonlinear permeable stretchable surface are assessed in the present study. The computational model of Casson fluid is used to define viscoelasticity, which is quantified rheologically in the momentum equation. Exothermic chemical reactions, heat absorption/generation, magnetic field and nonlinear volumetric thermal/mass expansion over the stretched surface are also considered. The proposed model equations are lessened by the similarity transformation to the dimensionless system of ODEs. The obtained set of differential equations are numerically computed through a parametric continuation approach. The results are displayed and discussed via figures and tables. The outcomes of the proposed problem are compared to the existing literature and bvp4c package for validity and accuracy purposes. It has been perceived that the energy and mass transition rate of viscoelastic fluid increased with the flourishing trend of heat source parameter and chemical reaction, respectively. Casson fluid velocity can be elevated by the rising effect of thermal, mass Grashof number and nonlinear thermal convection.

Overlapping grid SQLM for third-grade modified nanofluid flow deformed by porous stretchable/shrinkable Riga plate

Abstract The improvement in thermal performance of fluid and the control of energy loss are equitably significant. Therefore, the purpose of this study is to analyze entropy generation, stagnation point flow, and thermal characteristics of non-Newtonian third-grade modified hybrid nanofluid generated by a stretchable/shrinkable Riga plate in a porous medium with varying flow viscosity. In this analysis, a modification of hybrid nanofluid is considered by using pure water as a base fluid and three various nanomaterials (aluminium oxide, copper, and nickel) as nanoparticles in the characterization of heat transfer. Furthermore, the contribution of heat source/sink and viscous dissipation are accounted for in the model. The suited transformations are enforced to remodel the governing mathematical equations to produce ordinary differential equations that are conveniently tackled via spectral quasilinearization method (SQLM) along with the overlapping grid idea to yield numerical solutions. The preference of this approach over others has been justified through discussion of error bound theorems, residual and solution errors, computational time, and conditioning of matrices. The physical significance of disparate governing parameters on flow variables, velocity gradient, thermal rate, and entropy generation are scrutinized through graphs and tables. Crucial findings of the study include that temperature of the modified hybrid nanofluid enhances quickly (better thermal conductor) than temperature of single nanofluid, hybrid nanofluid, and conventional third-grade fluid for higher Biot number, variable viscosity, and heat source parameters. Mass suction enhances fluid flow and physical quantities of interest, but suppresses the fluid temperature. An increase in variable fluid viscosity, modified Hartmann number, and third-grade parameters enhances the wall drag coefficient while lowering the rate of heat transfer, and the opposite is true for porous media. More entropy is generated in the system by high variable fluid viscosity, suction, viscous dissipation, modified Hartman number, and non-Newtonian parameters. Owing to high velocity and temperature associated with modified hybrid nanoparticles, modified hybrid technology is recommended in enhancing the physical attributes of the fluid with minimal cost effects. In engineering and industrial point of view, this study can contribute significantly in thermal improvement of the working fluid.

Multiple linear regression analysis on the flow of ternary hybrid nanofluid by a quadratically radiated stretching surface with and second order slip

The addition of , and to increases thermal conductivity, which was around 1.14 at 45 °C for a 0.1 wt% concentration of the ternary hybrid nanofluid . Keeping this in mind, we explored a chemically reactive flow through an elongating sheet with quadratic thermal radiation and second-order slip. To achieve the desired results, bvp4c (Matlab built-in function) is used. The engineering parameters, including heat transfer rate, are discussed using Multiple linear regression. The primary finding of this study is that the radiation parameter, heat source parameter and Brinkman number all negatively influence the Nusselt number. It has been discovered that the first-order slip parameter reduces fluid velocity and the surface drag force decreases as the magnetic field parameter increases. It is noticed that there is a negative relationship between the Sherwood number and the chemical reaction parameter. Furthermore, the fluid concentration is found to have a proportionate relationship with the order of the chemical reaction. Validation is performed between the current and previous study outcomes to determine the accuracy of the present work.

Laser welding simulation of large-scale assembly module of stainless steel side-wall

Due to the advantageous characteristics of laser welding technology, it is being increasingly used for constructing stainless steel rail vehicles. It can improve the appearance of a vehicle, enable designs with a relatively high degree of flatness, and ensure higher-quality connections between different parts of a vehicle. Moreover, it can improve the strength and stiffness of the components of the vehicle. In this study, a large-scale assembly module of a stainless steel side-wall was considered as the research object. The combined heat source model of a Gaussian heat source and a cylindrical volume heat source was used to obtain the heat source parameters of laser welding to match the experimental data. Based on the thermal cycle curve method (TCCM), the influence of the number of weld segments and mesh divisions of the local model on the efficiency and accuracy of laser welding simulations was investigated. Thereafter, the research results were applied to the welding simulation of the whole side-wall module. The shape of the molten pool obtained using the combined heat source was closer to that of the experiments (error < 10%), demonstrating the accuracy and effectiveness of the developed the heat source model for laser welding simulation. For local model laser welding using the TCCM, a coarse mesh was used, and the weld was divided into four segments, and highly accurate results were obtained. This calculation time was only 5.97% of that of a moving heat source in case of the thermo-elastic-plastic method (TEPM). Residual stress and welding deformation of the stainless steel side-wall module were calculated according to actual process parameters and the results of local model simulation. Residual stress was discontinuously distributed at the weld segments, and it only slightly influenced the overall stress distribution. The maximum residual stress (462.15 MPa) occurred at the weld of the large crossbeam. Welding eight small and two large crossbeams influenced the deformation change and the maximum deformation (1.26 mm) appeared in the middle position of the left side-wall. The findings of this study show that the TCCM has high calculation accuracy and is sufficiently economical for predicting laser welding of large structures.

Temperature response in skin tissue during hyperthermia based on three-phase-lag bioheat model using RBF meshfree method

Various non-Fourier heat conduction models have been proposed to overcome the paradox of the infinite propagation speed of heat signals in Fourier’s law. The three-phase-lag (TPL) heat model is a non-Fourier model based on the linearized theory of coupled thermoelasticity that combines heat flux, temperature gradient, and thermal displacement gradient. The present paper proposes a novel method with meshfree and spectral nature to solve the two-dimensional three-phase lag (TPL) bioheat model for tissue heating during hyperthermia. In the space domain, radial basis functions (RBFs) and, in the time direction, shifted Chebyshev polynomials are employed to solve the model. The use of Chebyshev polynomials in the time direction enables one to get the solution in the whole time domain simultaneously with fewer nodes. Further, there is no need for background meshes in space due to the meshless nature of RBFs, and the proposed method is equally applicable to irregular domains. The proposed method is validated with the existing semi-analytical solution of the TPL model in one spatial dimension and found to be in good agreement. The temperature profile and the impact of various parameters, such as phase lag times, blood perfusion rate, and heat source parameters on heat transfer in tissue, have also been discussed.

Perturbation methodology for electromagnetic radiative fluxing of chemical reactive Casson fluid flow under heat source (sink) effectiveness

In this paper, magnetohydrodynamics of a Casson fluid flow is inspected with the presence of thermal radiation and chemical reaction. Employing the perturbation procedure, the modeling equations are tenacious; the graphs are acquired to illustrate the results. The Casson fluid velocity increases as the perturbation parameter increases. Grashof values for heat and mass transport enhanced Casson fluid velocity. Increasing Casson, magnetic, heat source, and radiation parameters reduce the flow velocity. Prandtl number, heat source, and radiation parameter all reduced the temperature profiles. Chemical reaction parameters lowered the concentration profiles. The skin friction enhances with Casson parameter impact. However, the skin-friction coefficient, Sherwood and Nusselt numbers reduce with an increment in the perturbation parameter. In certain cases, this study’s answers agreed well with the previous literature. Casson liquid with a magnetic region using mixed convection by an exponential vertical boundary layer is the novelty of the work.

Three-dimensional annular heat source for the thermal simulation of coaxial laser metal deposition with wire

Coaxial laser metal deposition with wire (LMD-w) is an innovative additive manufacturing technology in which a wire is coaxially fed through the center of a hollow laser beam into a laser-induced melt pool. This special configuration results in a direction-independent process, which facilitates the manufacturing of thin-walled metal components at high deposition rates. However, laborious experimental test series must be conducted to adjust the process parameters so that the substrate and the part do not overheat. Therefore, models are needed to predict the resulting temperature field and melt pool dimensions efficiently. This paper proposes a finite element simulation model using an innovative heat source, which considers the unique intensity distribution of the annular laser spot. The heat source parameters were calibrated experimentally based on fusion lines obtained from metallographic cross sections of aluminum alloy samples (AA5078 wire and AA6082 substrate). Subsequently, the temperature distribution in the substrate plate was measured by means of thermocouples to validate the developed model. It was shown that the proposed heat source replicates the heat input accurately. With the presented model, essential features for process development, such as the temperature field and the melt pool dimensions, can be reliably predicted. The model contributes to a better understanding of the LMD-w process and facilitates an efficient process development in future research work as well as for industrial applications. Key words: thermal simulation, annular laser spot, heat source, laser metal deposition, coaxial wire feeding, directed energy deposition

In this research, the unsteady MHD flow of a Casson fluid past a vertical plate that oscillates while maintaining a constant wall temperature and the heat source is the subject of this article. The fluid is electrically conductive and moves through a porous media. Partial differential equations with initial and boundary conditions are used to model this phenomenon. There are a few appropriate non-dimensional variables introduced. Using the finite difference method(FDM), the consistent dimensionless equations with circumstances are resolved. The energy and velocity equations are solved precisely. Expressions for Nusselt number and skin friction are also assessed. The outcomes of computations are analyzed for newly developing flow parameters. Additionally, skin friction and the Nusselt number effects are explained using table values. Furthermore, increasing the heat source parameter causes a rise in temperature and velocity.

Entropy Generation and Thermal Radiation Analysis of EMHD Jeffrey Nanofluid Flow: Applications in Solar Energy.

This article examines the effects of entropy generation, heat transmission, and mass transfer on the flow of Jeffrey fluid under the influence of solar radiation in the presence of copper nanoparticles and gyrotactic microorganisms, with polyvinyl alcohol-water serving as the base fluid. The impact of source terms such as Joule heating, viscous dissipation, and the exponential heat source is analyzed via a nonlinear elongating surface of nonuniform thickness. The development of an efficient numerical model describing the flow and thermal characteristics of a parabolic trough solar collector (PTSC) installed on a solar plate is underway as the use of solar plates in various devices continues to increase. Governing PDEs are first converted into ODEs using a suitable similarity transformation. The resulting higher-order coupled ODEs are converted into a system of first-order ODEs and then solved using the RK 4th-order method with shooting technique. The remarkable impacts of pertinent parameters such as Deborah number, magnetic field parameter, electric field parameter, Grashof number, solutal Grashof number, Prandtl number, Eckert number, exponential heat source parameter, Lewis number, chemical reaction parameter, bioconvection Lewis number, and Peclet number associated with the flow properties are discussed graphically. The increase in the radiation parameter and volume fraction of the nanoparticles enhances the temperature profile. The Bejan number and entropy generation rate increase with the rise in diffusion parameter and bioconvection diffusion parameter. The novelty of the present work is analyzing the entropy generation and solar radiation effects in the presence of motile gyrotactic microorganisms and copper nanoparticles with polyvinyl alcohol-water as the base fluid under the influence of the source terms, such as viscous dissipation, Ohmic heating, exponential heat source, and chemical reaction of the electromagnetohydrodynamic (EMHD) Jeffrey fluid flow. The non-Newtonian nanofluids have proven their great potential for heat transfer processes, which have various applications in cooling microchips, solar energy systems, and thermal energy technologies.

Effect of reinforcements on hardness and wear behaviour of the AISI 630 steel & fabrication of hybrid surface composite using GTA

ABSTRACT The hybrid surface composite of AISI-630 was fabricated with reinforced MoS2 and fly ash using a Gas Tungsten Arc (GTA) setup. The solid lubricant MoS2 was expected to improve the wear resistance, but it will reduce the hardness. Owing to the presence of various oxides, the flyash was expected to improve hardness and wear resistance. The specific importance of this project is to find out the effect on the hardness and wear resistance of hybrid surface composite with the reinforcement of MoS2 and flyash in equal volume. The heat source parameters were optimised using the minimum percentage reduction in hardness and bead characteristics. Compared to the parent metal, the microhardness of the artificially aged hybrid surface composite surface increased by 34% and the wear rate reduced by 53%. The fabricated hybrid surface composite morphology and the reinforcement presence were investigated with optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffraction techniques.

Study Of Nanoparticle Dispersion In Capillaries Using Power Law Nanofluid Model

This paper investigates the aspects of dispersion of nanoparticles in blood capillaries linked to nanodrug delivery systems. Nanoparticles are injected intravenously in blood capillaries and the resultant fluid has been identified as nanofluid. The viscosity of nanofluid is modelled using the nanoparticle size dependent viscosity relation. The properties of blood are studied using power law fluid, owing to their physically close simulations. The dispersion model framed here has been solved applying the method used by Sankarsubramanian and Gill for deriving exchange coefficients. The study conducted gives an insight into temperature, velocity and three transport coefficients of nanoparticles dispersed in blood with respect to various parameters like heat source parameter, volume fraction, power law index, size of nanoparticles, Grashof number, Darcy number and slip parameter for small values of wall absorption parameter under steady state conditions. MATLAB software has been used to plot the graphs. The outcomes reveal that physical properties of nanoparticles like size chiefly govern their dispersion. Convergence analysis is also stated for the inhomogeneous Bessel differential equation obtained while solving the problem. The developed mathematical model has useful applications to understand the dispersion of nanodrugs in the treatment of cardio vascular diseases.
