Irreversibility intent triple diffusion stream over porous medium plate with radiation and joule heating

The influence of thermal radiation and Joule heating on the entropy inception by triple diffusion over the permeable plate is examined, as well as its influence on other physical aspects of the problem. The radiative and Joules heating effects are being investigated using a mathematical model. The irreversibility caused variations in entropy inception due to fluid, heat fluxes, and solute concentration of salts utilized. The non-dimensioned modeled equations were interpreted numerically by shooting approach using Runge-Kutta-Fehlberg scheme. Numerical outcomes were plotted in the form of graphs for flow and thermal distributions, entropy inception rate, and Nusselt number because of suction/injection through the plate, and the results of concentration based parametric analysis were plotted out for local entropy inception rate, local Bejan number, local mass Bejan number and local irreversibility ratio based on assisting flow and opposing flow. Local mass Bejan number underwent some interesting aspects, such that it behaves opposite to local Bejan number to enhance for magnetic, radiation parameter in suction/injection situations. In the suction/injection flow conditions, the entropy inception rate gets enhanced for most of the flow and thermal parameters like magnetic, radiation, convective parameters, Eckert number, buoyancy parameters of solutes 1 and 2, and temperature ratio parameter. Because of influences of assisting and opposing flow, the entropy inception rate gets slowed down by the effects of Lewis numbers of solutes 1 and 2 and Darcy number. Reynolds number has the influence assisting the entropy rate to increase.
