Simulation analysis of MHD hybrid CuAl ₂ O ₃ /H ₂ O nanofluid flow with heat generation through a porous media

Abstract

Summary Hybrid nanoliquids comprise of better physical strength, mechanical resistance, thermal conductivity, and chemical stability as equated to individual nanoliquids. The present work investigates the MHD laminar flow, containing hybrid nanoparticles, with heat transfer phenomenon over a stretching sheet immersed in a porous medium. The effect of induced magnetic field has also been taken into account. The flow model PDEs are rehabilitated into ordinary ones using a persuasive tool of similarity variables. The analogous system of dimensionless equations alongside the boundary conditions is numerically treated with the Successive‐Over‐Relaxation (SOR) technique. Flow and heat transfer aspects of both pure and hybrid nanofluids are examined for the preeminent parameters. Our outcomes are associated with the previously accomplished experimental and numerical results, and found to be in a good agreement with them. As a major outcome of the study, it has been noted that, apart from their well‐reported thermal characteristics, hybrid nanofluids are capable of raising the shear stress to remarkably higher levels (upto 57% in some cases). Therefore, such fluids must be used with caution in applications where a control on the shear stress is required.

Impact of thermal radiations, heat generation/absorption and porosity on MHD nanofluid flow towards an inclined stretching surface: Non‐similar analysis

“…Shahid et al [34] employed a vertically stretched porous sheet to study the temperature dependency of the viscosity of an MHD Darcy-Brinkman-Forchheimer nanofluid inside the Buongiorno model. To study the behavior of an MHD hybrid nanofluid, Ali et al [35] used a porous stretching sheet. Considering the existence of non-uniform heat sources and sinks, Ge-JiLe et al [36] examined MHD radiative ferrofluid flow over a cone.…”

Significance of radiant-energy and multiple slips on magnetohydrodynamic flow of single-walled carbon nanotube-water, titanium dioxide–water, multiwalled carbon nanotube–water, graphene oxide–water nanofluids

“…Some related investigations on nanofluid flow are available in the literature. [2][3][4][5][6][7][8][9][10][11][12] CNTs are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms. CNTs show unique properties such as high electrical conductivity, mechanical strength, and large current carrying capacity.…”

A numerical investigation of cross‐diffusion on magnetohydrodynamic Cu‐Al2O3/H2O hybrid nanofluid flow over a stretching sheet with chemical reaction

“…MHD Cu-Al 2 O 3 / H 2 O HNF flow simulation analysis has revealed the remarkable capability to elevate shear stress to unprecedented heights. 18 The HAM solution was investigated for MHD slip flow and HT in an UCM fluid under the effect of suction/injection due to a stretching sheet by Guled et al 19 A significant number of modern and aviation applications operating at high temperatures involve thermal radiation. Recently, thermal convection coupled with various NP mixtures has attracted the attention of numerous researchers, as it can significantly influence convective HT coefficients.…”
