Exothermic impact on Eyring-Powell nanofluid flow through a heated surface embedded in porous medium with thermal radiation: a numerical study

Abstract

The foremost aim of our study is to discuss the unsteady 2D MHD Powell-Eyring flow produced by a flat stretching surface. An incompressible chemical reactive MHD Eyring- Powell fluid immersed in porous medium filled the convective heated stretched sheet with the appearance of nanoparticles. A thorough in- vestigation is performed to study impacts of exothermic, first order chemical reactions and thermal radiation on the fluid flow. This study also assesses the heat and mass boundary conditions. The model utilized for nanoliquid elaborates the influence of thermophoresis and Brownian motion. Moreover, an efficient finite difference method is used and a numerical solution is obtained for the resulting nonlinear PDEs with appro- priate boundary conditions. A detailed discussion regarding how the principal variables affects the flow and thermal fields, is carried out. It is also discussed that how the flow and heat transfer processes is affected by the various parameters of interest. In addition to all this, the physical quantities such as Nusselt number, drag coefficient and mass transfer are calculated keeping in view their significance in engineering.

Soret effect on stability of Darcy problem in a bidispersive porous medium with an exothermic chemical surface reaction

“…For accurate modelling of exothermic reactions in such reactors, it is necessary to account for the effects of convection. Thus, the justification for incorporating a convection model in studies of porous media with exothermic chemical surface reactions lies in its enhanced ability to simulate the complex interplay between heat transfer, fluid flow, and reaction kinetics, providing insights that are closer to real-world phenomena [31,32].…”

“…Furthermore, the same author Riaz et al [41] highlighted the heat effect on MHD Maxwell fluid by using local and nonlocal operators. Some other associated references dealing with fractional differential operators, MHD Maxwell fluid movement, heat emission, or fractional second-grade fluid are given in [42][43][44][45][46][47][48][49][50][51][52][53][54].…”
