Influence of Radiation on Magneto-hydrodynamics Flow Over an Exponentially Stretching Sheet Embedded in a Thermally Stratified Porous Medium in the Presence of Heat Source

Abstract

The influence of radiation on magneto-hydrodynamics (MHD) boundary layer flow over an exponentially stretching sheet embedded in a thermally stratified porous medium in the presence of heat source and suction/blowing was investigated. Similarity transformation was used to convert the governing equations from partial differential equations into a system of non-linear ordinary differential equations. Solving numerically, we used shooting method along with fourth order Runge-Kutta technique to obtained numerical values. The effects of the obtained numerical values of the dimensionless parameters on skin-friction coefficient, Nusselt number, velocity profile and temperature profile are illustrated in table and graphs plotted using MATLAB. Comparison of the velocity profile with previously published work was presented and found to be in good agreement.

Arrhenius kinetics driven nonlinear mixed convection flow of Casson liquid over a stretching surface in a Darcian porous medium

“…In addition to this, the theoretical investigations on mixed convection flow of non-Newtonian fluids over a stretching material problem might have enormous economic and energy saving implications for the industries that involve extrusion of molten polymers, hot rolling, food stuffs processing, paper production, and glass fibre production. The Newtonian/non-Newtonian fluid flow problems over a stretching surface in a porous medium have attracted many researchers in recent years [ [19] , [20] , [21] , [22] , [23] , [24] ].…”

Casson fluid flow with heat generation and radiation effect through a porous medium of an exponentially shrinking sheet

“…It was observed that the boundary layer thickness reduces with increase in Casson parameter values. Recently, (Senge et al, 2021) investigated MHD flow over an exponentially stretching sheet embedded in a thermally stratified porous medium.…”
