Ternary cobalt ferrite (CoFeO4)-silver (Ag)-titanium dioxide (TiO2) hybrid nanofluid hydromagnetic nonlinear radiative-convective flow from a rotating disk with viscous dissipation, non-Darcy and non-Fourier effects: Swirl coating simulation

Magnetic nanoparticles are increasingly being deployed in smart coating systems due to their exceptional functionalities and abilities to be tuned for specific environmental conditions. Inspired by the emergence of tri-hybrid magnetic nanofluids which utilize three distinct nanoparticles in a single base fluid coating, the present article examines analytically and computationally the swirl coating of magnetic ternary hybrid nanofluid from a rotating disk, as a simulation of spin coating deposition processes in materials manufacturing. Owing to high temperature fabrication conditions, thermal radiative heat transfer is also considered and a Rossleand flux model deployed. -- hybrid nanoparticles are considered with Ethylene Glycol-Water () base fluid. A filtration medium is also featured (porous medium) adjacent to the disk and the Darcy-Forchheimer model is deployed to simulate both bulk matrix porous drag encountered at lower Reynolds numbers and inertial quadratic drag generated at higher Reynolds numbers. Thermal relaxation of the coating nanofluid is additionally addressed and a non-Fourier Cattaneo-Christov model is therefore implemented in the heat conservation equation. Viscous dissipation is also included in the model. The governing conservation equations for mass, momenta (radial, tangential and axial) and energy with prescribed boundary conditions are rendered into coupled nonlinear ordinary differential boundary layer equations via suitable scaling variables and the Von Karman transformations. The derived reduced boundary value problem is then solved with a Runge-Kutta numerical scheme and shooting scheme in MATLAB. Validation of solutions is included with previous studies. Radial and azimuthal velocities, temperature, radial skin-friction, azimuthal skin friction and local Nusselt number are computed for a range of selected parameters. A comparative assessment of mono nanofluid Hybrid - nanofluid and tri-Hybrid -- nanofluid is conducted. This combination of hybrid nanoparticles has never been examined previously in the literature and constitutes the significant novelty of the present work. Both radial and tangential velocity are depleted with increasing applied magnetic field whereas temperature and thermal boundary layer thickness are increased.

Implicit finite difference simulation of non-similar conduction–convection interaction of magnetohydrodynamics water-Cu nanofluid flow along a vertical surface

Heat-exchanging devices equipped with conventional thermal fluids are failing to meet the standard in terms of thermal efficiency. The inclusion of nanoparticles within a base fluid to improve thermal efficiency can be a great alternative but a proper understanding on the interactions during the heat transfer phenomena is required. This work examines the interactions between conduction and convection in a nanofluid of water and copper (Cu) particles. The investigation focuses on the behavior of the nanofluid, considering the impact of magnetohydrodynamics (MHDs) flow over a vertical surface. The governing equations were non-dimensionalized by the suitable transformation and then were solved numerically by the implicit finite difference method (FDM). The key findings suggested that increasing magnetic parameter plummeted skin friction coefficient and accelerated the heat dissipation up to by augmenting the peaks of fluid velocity as well as the temperature under a constant volume fraction of nanoparticles. In addition, the thermal boundary layer thickness also increased concurrently. Alternatively, when a constant non-zero magnetic parameter was considered, and volume fraction of nanoparticles was allowed to vary, the convective heat transfer got enhanced. The findings from this study will assist the relevant industry to identify the suitable fraction of Cu nanoparticles in the presence of magnetic field in order to achieve the best thermal efficacy of a heat-exchanging unit.

Effect of RIBS/FINS and Aspect Ratio on Flow Boiling Characteristics in Conventional Channels

Abstract In this work, experiments are conducted with conventional rectangular channels of two different aspect ratios (AR = w/d) for the horizontal boiling flow conditions at atmospheric pressure. Distilled water was used as the working substance. The heat transfer coefficients (HTC) were measured for mass fluxes and heat fluxes ranging from 85.94 kg/m2-s to 343.77 kg/m2-s and 10 kW/m2 to 100 kW/m2, respectively, and at inlet subcooled temperatures of 303 K, 313 K, and 323 K. Visualization of the boiling phenomenon was done using a high-speed camera for the two channels under similar conditions. The results show that the AR has a dominant effect on the HTC. At low heat flux values, higher HTC was noticed for the channel of higher AR (AR = 1.25) whereas, at high heat flux conditions, the HTC is higher for the channel of lower AR (AR = 0.2). With an increase in inlet subcooled temperature, the HTC decreased for both channels due to increased thermal boundary layer thickness and reduced bubble formation. Further, the channel of AR = 1.25 with ribs/fins performed better than the smooth channel due to the high bubble nucleation rate.

Unsteady Hiemenz Flow of Cu-SiO2 Hybrid Nanofluid with Heat Generation/Absorption

The use of hybrid nanofluid as an alternate heat transfer fluid has shown great potential, and ongoing research to improve its thermal conductivity is important. This study focuses on the impact of heat generation/ absorption on the unsteady Hiemenz flow of aqueous hybrid nanofluid containing copper and silica nanoparticles. Mathematical equations for the hybrid nanofluid model are derived using suitable similarity transformations and solved numerically using bvp4c codes in Matlab software. The results indicate that increased heat generation/absorption leads to an increase in both momentum and thermal boundary layer thickness. The effects of suction and nanoparticle concentration are also analysed and presented graphically. Additionally, a stability analysis is also performed, which discloses that the first solution produced is stable, however, the second solution is not. The findings of this study provide valuable insights into the behaviour of hybrid nanofluid in unsteady flow and can aid in the development of more efficient heat transfer fluids for various engineering applications.

Unsteady Boundary Layer Heat and Mass Transfer Flow of Nanofluid Over Porous Stretching Sheet with Non-Uniform Heat Generation/Absorption and Double Stratification

The influence of thermal radiation and stratification process on unsteady MHD flow over stretching sheet embedded in “nanofluid saturated porous medium with non-uniform heat source/sink was analyzed numerically in the present analysis. Proper similarity transformations reduce the nonlinear partial differential equations into ordinary differential equations and are solved numerically by using Galerkin Finite element method. Impact of different parameters, such as, magnetic parameter (0.1–1.0), buoyancy ratio parameter (0.1–4.5), radiation parameter (0.5–1.7), Rayleigh number (0.1–0.7), thermophoresis parameter (0.4–1.5), thermal stratification parameter (0.01–1.0), Brownian motion parameter (1.0–2.0), solutal stratification parameter (0.01–1.0), unsteadiness parameter (0.1–0.4), space–dependent (-0.5–0.4) and temperature dependent (-0.5–0.2) heat source/sink parameters on velocity, temperature and concentration profiles is calculated and are illustrated graphically. Skin-friction coefficient, Nusselt and Sherwood number are calculated and the results are shown in tabular form. It is found that the thermal stratification parameter deteriorates the temperature of the fluid. The concentration of the fluid diminishes with rising values of solutal stratification parameter. The thermal boundary layer thickness elevates” with higher values of Brownian motion and thermophoresis parameters.

Stagnation point on MHD boundary layer flow of heat and mass transfer over a non-linear stretching sheet with effect of Casson nanofluid

ABSTRACT The present study analyzes the effects of the magnetohydrodynamic stagnation point and Casson fluid flow considered over the stretching surface. Due to the growing need for non-Newtonian nanofluid flows in industry and engineering areas, the present work focuses on the Casson nanofluid flow over a non-linear stretching surface with effects. The Casson nanofluid is more helpful for cooling and friction-reducing agents compared to Newtonian-based nanofluid flow. The mathematical explanation of the problem is elaborated with the help of partial differential equations. The coupled nonlinear form of ordinary differential equations (ODEs) is solved numerically by the Keller-Box method using a suitable MATLAB program. On the effect of the Casson parameter on the velocity parameter, it is observed that for large values of the Casson parameter, the velocity profile decreases. The reason behind this behavior is that increasing the values of the Casson parameter increases the fluid viscosity, i.e. reduces the yield stress. Therefore, the momentum boundary layer thickness reduces and the thermal boundary layer thickness increases.

Casson fluid flow with heat generation and radiation over a non-linear stretching sheet

This study investigates Casson fluid flow with heat generation and radiation over a non-linear stretching sheet. The resulting partial differential equations are converted to a system of ordinary differential equations using similarity transformation and solved numerically using shooting technique with fourth order Runge-Kutta method. The effect of radiation, heat source, and Casson parameters on the momentum and thermal boundary layers are examined through graphs using MATLAB. From the graphs it is seen that increase in the values of heat source and Prandtl number parameter increases the temperature profiles. The momentum boundary layer thickness decreases while the rate of heat transfer increases with increasing non-linear parameter. The temperature and thermal boundary layer thickness decreases with increasing radiation parameter values.

Flow and Heat transfer of Hybrid nanofluid past an Exponentially Stretched Porous surface

This research looks at the flow and heat conduction properties of a hybrid nanofluid formed by an exponentially stretched porous surface. Over the last decade, there has been a substantial increase in research on nanofluids. Despite several contradictions in the published results and a poor understanding of the heat transmission mechanism in nanofluids, this fluid has emerged as a viable heat transfer medium. It takes longer for the combination nanofluid to make heat than it does for ordinary nanofluid. It has also been shown through simulations that the mixed nanofluid has better temperature performance than the nanofluid. Using the similarity transformation approach, the governing equations of the issue are turned to similarity equations. To convert nonlinear partial differential equations (PDEs) to ordinary differential equations (ODEs), the Keller Box approach is used. This strategy for solving these ODEs has been shown to be quite successful. The effects of several targeted parameters on physical quantities are shown, and the comparison of findings for validation is also recorded. The study's findings are provided as graphs, demonstrating the strong influence of the targeted elements on both nanofluid and hybrid nanofluid. Because of the existence of hybrid nanofluid, the velocity and temperature profiles have improved. Variations in the amount of Copper (Cu) nanoparticles, in particular, cause dramatic variations in the velocity and temperature profiles of the hybrid nanofluid. Furthermore, a lower Prandtl number is shown to reduce temperature and thermal boundary layer thickness. The graphical representations also show how porosity affects temperature and velocity profiles.

Dual Stratification Effects on Mixed Convective Electro-magnetohydrodynamic Flow over a Stretching Plate with Multiple Slips and Cross Diffusion

This paper analyzed the effects of dual stratification on mixed convective electro-magnetohydrodynamic flow over stretching plates with multiple slips. With the aid of the similarity transformation technique were, the governing boundary equations, that were partial differential equations, were changed to a couple of ordinary differential equations and then solved with fourth order Runge Kutta method and Newton’s Raphson shooting techniques. It was observed that the magnetic field, Buoyancy ratio, permeability, momentum slip parameters, Dufour, Soret and Brinkmann numbers made the thermal boundary layer thickness to increase but the solutal stratification, electric field, chemical reaction, solutal slip, suction, thermal slip and thermal stratification parameters, Prandtl, Richardson and Lewis number decreased the thickness of the thermal boundary layer. The Buoyancy ratio, permeability, momentum slip, thermal slip and thermal stratification parameters and Soret number enhanced the solutal boundary layer thickness.

Large-eddy simulation of non-isothermal flow and heat transfer in an enclosed rotor–stator cavity

This paper presents a numerical study of non-isothermal flow and heat transfer in an enclosed rotor–stator disk cavity. Wall-resolved large-eddy simulation is implemented with attention focused on the Reynolds number effect (Reϕ=105 and 5×105) and non-isothermal effects, including different thermal Rossby numbers (βΔT=0.05–0.25) and heat convection types (axial heat convection, axial and radial heat convection). Verification and validation are implemented by comparing with available experimental data and examining the resolution of the present LES. Although the Batchelor flow type is unchanged, the non-isothermal effect is found to be responsible for the acceleration of flow in both disk boundary layers and cavity core. Temperature in the cavity is negatively correlated with the Rayleigh number. The radial inward temperature gradient is found to be responsible for destabilizing the flow near the cylinders, due to the effect of centrifugal buoyant force. Transition from laminar to turbulent is shown in the rotor boundary layer for Reϕ=5×105 conditions. The non-isothermal effect increases flow unsteadiness in both rotor and stator boundary layers, but it has little to no effect on the transition position, as well as the kinematic and thermal boundary layer thicknesses, which are mainly controlled by Reϕ. Spectral proper orthogonal decomposition is implemented to explore the Reynolds number effect. Analyzing the most energetic mode and its energy spectra provides some insights into the understanding of non-isothermal rotor–stator disk cavity flows.

Insight into jet-regeneration composite cooling technology employed in scramjet: Significance of relative positions of two jet holes

Due to the further increase in hypersonic vehicle speed, the scramjet faces supersonic combustion and aerodynamic heating, and the conventional single cooling method like regenerative cooling has been unable to meet the heat dissipation requirements of scramjet. The composite cooling system has become the hotspot of recent research. Jet cooling has a good cooling effect at high heat flux, so the jet-regeneration composite cooling method is innovatively proposed in this study. Compared with other composite cooling systems, the jet impingement can effectively weaken thermal boundary layer thickness. Initially, the total performance of the jet-regeneration composite cooling was experimentally verified via subcritical air. Furthermore, the numerical simulation of the jet-regeneration composite cooling was also carried out after the validation of turbulence models and mesh independence. Further examples, such as the jet impingement under the effect of the initial mainstream (so-called jet-mainstream) and regenerative cooling (so-called mainstream-only), are used to illustrate the advantages of this composite cooling (so-called jet-only). The heat transfer coefficient of jet-only is 2.6 times larger than that in the case of jet-mainstream. Compared with traditional regenerative cooling, even under the influence of the mainstream, the boundary layer thickness at the stagnation point of the jet impingement can be reduced by 40 times. This work is beneficial to the design of the jet-regeneration composite cooling system.

Regulation mechanism of bionic wireless power device thermal management system based on nanofluids and magnetic field

For further optimal power conservation and dissipation performance of wireless power devices, this paper presented a cooling system that couples a wave bionic surface structure with composite magnetic nanofluids. Heat transfer mechanisms near the wall of the channel under magnetic field excitation have been developed. Effect of changes in the near-wall thermal boundary layer on the integral heat transfer was analyzed, and a comprehensive evaluation of the model performance was given. The outcomes revealed that as the flow approaches the crest, the difference in thermal boundary layer thickness for different flow Reynolds numbers becomes small, and in the flow region in the second half of the wave crest, the thermal boundary depth is no longer regular at different Reynolds numbers, which is due to the “detached flow”. “Detached flow” effectively breaks the thermal boundary enhancing the heat transfer performance. Temperatures excited by magnetic forces show disordered “jumps”, and the heat transfer characteristics are substantially improved by 41.59 % under magnetic field. Comprehensive evaluation index under magnetic field excitation is up to 1.54 for wave bionic surfaces with a frequency of 20 rad/s.

Numerical analysis of electro-thermo-convection in a differentially heated square cavity with electric conduction

Natural convection with an electric field in the classic differentially heated square cavity is numerically studied. The electric conduction model for the generation of free space charges, which applies to weak and moderate electric field with weakly conducting liquids, is specially considered. The whole set of governing equations is implemented in the open-source finite-volume framework of OpenFOAM. Thorough investigation has been undertaken to analyze the thermal and flow characteristics of electro-thermo convection. The results reveal that the introduction of an electric field leads to a suppressive influence on flow motion across all considered Rayleigh numbers (Ra), aligning with recent experimental findings. This effect becomes more pronounced with increasing conduction number (C 0), resulting in the reduction of flow intensity and a thicker thermal boundary layer. Consequently, heat transfer is subdued due to the electric field, causing a decrease in the Nusselt number (Nu) as C 0 increases. To elucidate the mechanism how the electric field impacts natural convection, the torques induced by the electric and buoyancy forces are computed. Higher C 0 will lead to a lower buoyancy torque and stronger electric torque, where the electric torque is opposite to the buoyancy torque, thus the weaker flow strength is shown at higher C 0. Finally, to quantify the reduction in heat loss, the relative Nusselt number (Rnu) is introduced. It is found that there is a critical Ra corresponding to minimal Rnu, and for the parameters considered in this study, the minimum Rnu of 0.563 is observed at C 0 = 0.2 and Ra = 1.2 × 104. For large Ra, the Rnu almost keeps constant with increasing Ra.

Dual solutions of aqueous Ti-alloy & MWCNT hybrid nanofluid: A stability test

The flow and heat transfer induced by an exponentially shrinking sheet with Ti-alloy & MWCNT hybrid nanofluid are investigated in this paper. Additionally, this investigation focuses on the flow separation of hybrid nanofluid with an inclined magnetic field, thermal buoyancy force, and Joule heating effect. The Tiwari and Das model is used to formulate the hybrid nanofluid mathematical model. Suitable similarity transformations convert partial differential equations (PDEs) into a system of ordinary differential equations (ODEs). The resultant system is numerically solved by implementing the shooting approach along with the RK-4 technique. Multiple solutions are found for this current problem, and intriguingly, the velocity and temperature profiles of these two solution branches exhibit opposing characteristics. In conclusion, conducting a stability study on these two alternative solutions is worthwhile to determine which solution is more realistic and stable. The temporal stability test reveals that only the first solution is stable or physically valid. The important outcomes of this study, based on the stable solutions, are as follows: (i) velocity (temperature) is found to be higher (lower) when thermal buoyancy is absent and it is found to be lower (higher) for opposing thermal buoyancy; (ii) the skin friction coefficient and rate of heat transfer are found to be better for aiding thermal buoyancy and lower for opposing thermal buoyancy; and (iii) the thickness of momentum and thermal boundary layers is thinner for the first solution than the second solution. Furthermore, in this work, the flow patterns (streamlines) are investigated. The flow separation point is finally located. This current study revealed strong consistency with previous research. These types of studies are very useful in the areas of medical and aerodynamic science.

Study of Casson nanofluid flow over a wedge with variable magnetic effect, thermal radiation, and melting effects

In this article, we investigated the flow of a Casson nanofluid on a wedge considering the external effects of magnetic effects, thermal radiation, and melting effects. Also, thermophoretic and Brownian effects were being considered in our study. Similarity transformations were implemented to the governing set of nonlinear PDE’s to obtain coupled nonlinear set of ordinary differential equations. A fourth-order accurate MATLAB bvp4c routine was applied for solving the given boundary value problem. An excellent agreement to previously published results was found, which validates our study. Graphically, the consequences of pertinent parameters on dimensionless velocity, temperature, and nanoparticle concentration have been presented along with streamline visualizations for some of the parameters while the values for local skin friction, heat transfer, and mass transfer rates are presented in a tabular form. An augmentation in melting parameter augments momentum, thermal and concentration boundary layer thickness while skin friction, heat and mass transfer rates report a decrease. Wedge angle parameter, radiation, and Casson nanofluid parameters also enhance fluid velocity though the effects of magnetic field and permeability of the medium shows a reverse trend to their usual behavior.

Squeezing flow in the existence of carbon nanotubes past a Riga plate

Squeezing or squeeze flows have tremendous applications in applied fields, like engineering, biomedical sciences and rheological studies. This paper demonstrates the squeezing flow of kerosene-based nanoliquids between parallelly aligned plates, with a Riga-type fixed lower boundary. The effects of dispersing two types of copper-functionalized carbon nanotubes (CNTs), single-walled CNTs (SWCNTs) and multi-walled CNTs (MWCNTs) are examined. Using appropriate transformations, a self-similar ordinary differential system is derived from the governing model of partial differential equations and substantial boundary conditions. Using the homotopy analysis method (HAM) and the [Formula: see text] package, analytical and numerical estimates are obtained, respectively. For higher values of the squeezing parameter, dimensionless temperature increases, while velocity patterns are upside-down. Moreover, increments in dimensionless parameters representing Riga constituent width, modified Hartmann number, nanoparticle concentration and radiation parameter improve heat transfer rates and thermal boundary layer thickness, however, adversely affect velocity. Despite enhanced friction effects, numerical results show that the Nusselt number increases as nanoparticle loads and radiation parameters increase. This suggests that convection rates are improved over conduction rates. Excellent agreement is found between analytical and numerical evaluations. Apparently, it is noticed that MWCNTs perform better than SWCNTs.

Computation of couple stress electroconductive polymer from an exponentially stretching sheet

Magnetic polymer processing involves multiple physical phenomena and requires simultaneous consideration of rheological, hydromagnetic and thermal characteristics. Inspired by new developments in functional magnetic coating dynamics, the present article investigates the viscous magnetohydrodynamic non-Newtonian boundary layer flow of an incompressible, electrically conducting, couple stress, electroconductive polymer from an exponentially stretching sheet. The nonlinear boundary value problem is solved numerically by adopting shooting technique and bvp4c algorithm available in MATLAB software. Validation with the Adams-Moulton 2-step predictor corrector algorithm is included. The effects of non-Newtonian couple stress parameter, magnetic interaction number, mixed convection parameter, slip parameter, Prandtl and Eckert number on the primary and secondary velocities and temperature fields are visualized graphically. Greater hydrodynamic slip effect initially boosts the primary velocity near the wall but thereafter induces a decrement in it. However, a consistent improvement in secondary velocity is computed for greater slip parameter. Increasing Hall parameter strongly accelerates the secondary flow but only weakly accelerates the primary flow. Increasing magnetic interaction number decelerates the primary and secondary flow. Elevating magnetic number promotes the thermal boundary layer thickness and also the temperature. Couple stress effects generally accelerate both the primary and secondary flow.

Heat generation and radiative effects on time-dependent free MHD convective transport over a vertical permeable sheet

This paper investigates the role of heat absorption or production on time-dependent free MHD convective transport over a vertical porous plate with thermal radiation. The PDEs are changed into non-dimensional couple ODEs by adopting proper similarity analysis. Then the finite difference method (FMD) is used for solving the converted non-dimensional coupled ODEs. The roles of the dimensionless parameters or numbers like the radiative parameter (R), internal heat absorption or generation(Q), the suction (v0), the magnetic force parameter (M), the Schmidt number (Sc), and Prandtl number (Pr) the on the numerical results of the temperature, velocity, and concentration distributions are explained in graphically. The results indicate that improving values of the heat absorption or production with thermal radiation improves the thermal boundary layer thickness. The local skin friction coefficient increases by about 11 % and the heat transfer rate reduces by about 85 % due to improving values of Q from 1.0 to 2.0. Growing values of the radiative parameter from 1.0 to 4.0 improves the local skin friction coefficient by about 13 %. The heat transfer rate lessens by about 41 %. Our numerical results are more compared with the published paper.

Numerical Analysis of Magnetohydrodynamic and Dissipated Hybrid Casson Nanofluid Flow Over an Unsteady Stretchable Rotating Disk with Cattaneo-Christov Heat Flux Model

The study scrutinized MHD and dissipated (SWCNTs-Fe3O4)/C2H6O2 hybrid Casson nanofluids flow over an unsteady stretchable rotating disk with a Cattaneo-Christov heat flux model. By means of proper similarity conversion, the boundary layer flow governing PDEs was changed into systems of dimensionless coupled nonlinear ordinary differential equations. Subsequently, the consequent nonlinear momentum and energy equations with their boundary conditions were worked out numerically employing the spectral quasilinearization method (SQLM). The convergence, stability, and accuracy of the SQLM were established as a computationally efficient method to solve a coupled system of boundary layer problems. It is specified that 5% of SWCNTs, 20% of Fe3O4, and 75% of C2H6O2 being taken for the preparation of (SWCNTs−Fe3O4)/C2H6O2 hybrid nanofluid with shape factor n1 = n2 = 3, and the values of the parameters used are fixed to M = 5, S = 0.5, β = 5, κ = 0.5, Ec = 2, Λ = 2, Pr = 7.3, α = 0.5, δ = 0. The effects of more perceptible parameters on velocity and thermal flow fields were considered and scrutinized carefully via graphs and tables. The results disclose that the momentum and thermal boundary layer thickness markedly declined with more value of the unsteady parameter. The local heat transfer rate improves nearly by 14% as 0.2 volume of Fe3O4 nanoparticles dispersed in 0.05 volume of SWCNTs and 0.75 volume of C2H6O2 nanofluid, hence, in realistic uses adding more values of nanoparticles in the hybrid nanofluids is useful to progress the heating process. The study is novel since to the best of the author’s knowledge, no paper has been published so far on the unsteady flow of (SWNT-Fe3O4)-Ethylene glycol hybrid Casson nanofluid with the effects of the Cattaneo-Christov heat flux model. As well, the model used for the thermophysical properties of the hybrid nanofluid is a new approach. Generally, hybrid nanofluids of (SWCNTs-Fe3O4)/C2H6O2 show better flow distributions with good stability of thermal properties than their mono counterparts.

Flow reversal for hybrid nanofluid with heat generation and slip effect in Darcy porous medium: The stability analysis

This investigation focuses on the flow reversal and separation of hybrid nanofluid, with heat generation and first-order velocity slip, in a Darcy porous medium. The Choi–Eastman nanofluid model is used to formulate the hybrid nanofluid mathematical model. Suitable similarity transformations convert partial differential equations into a system of ordinary differential equations. The resultant systems are numerically solved by implementing the shooting approach. Multiple solutions are found for this current problem, and intriguingly, the velocity and temperature profiles of these two solution branches exhibit opposing characteristics. In conclusion, conducting a stability study on these two alternative solutions is worthwhile to determine which solution is more realistic and stable. The temporal stability test reveals that only the first solution is stable or physically valid. The important outcomes of this study, based on the stable solutions, are as follows: (i) the hybrid nanofluid’s Nusselt number, skin friction, and velocity rise when the inclined magnetic parameter rises, (ii) the value of the smallest eigenvalue increases with higher values of the inclined magnetic parameter, and (iii) the thickness of momentum and thermal boundary layers is thinner for the first solution than the second solution. Additionally, the identification of flow separation and reversal points is valuable for aerospace technology, following the Prandtl theory. Finally, this study provides streamlined patterns to enhance the understanding of fluid flow behavior.
