Thermal radiation effect on thermostatically stratified MHD fluid flow through an accelerated vertical porous plate with viscous dissipation impact

Abstract

This research analyzes the unsteady MHD flow via a porous medium past an accelerating vertical plate in a thermally stratified flow of fluid in the existence of viscous dissipation. The medium under consideration is assumed to be a non-scattering, gray fluid that absorbs and emits radiation. The governing equations are discretized by employing the finite difference approach (FDM) by utilizing MATLAB software. Graphs and a table are used to exemplify the impact of flow factors on velocity and temperature profiles. The findings indicate that a decrease in velocity and an increase in temperature occur whenever the magnetic field parameters are increased. Both the velocity and the temperature will decrease as the stratification factor increases. As the Radiation parameter is increased, the temperature profiles decrease.
