Description
Summary:The thermodynamics analysis of a reactive hydromagnetic radiative heat transfer flow within a channel filled with saturated non–Darcy porous medium with convective cooling of the walls is investigated for Arrhenius kinetics. The momentum and energy equations governing the fluid flow are modeled, non-dimensionalised and solved analytically by making use of modified Adomian decomposition Method (MADM). The expressions of momentum and energy profiles are used to analysed the entropy generation rate and the impacts of other flow thermophysical parameters especially the radiative flux on the fluid flow including the thermal stability analysis obtained using Padé approximation technique are presented and discussed.
