Analysis of Entropy Generation for MHD Heat Transfer Flow of Viscous Fluid Embedded in a Porous Channel Due to Thermal Radiation

Abstract

The study investigates the effect of convective flow on entropy generation for MHD heat transfer flow of viscous fluid embedded in a porous channel due to thermal radiation. The governing equations were transformed using the non-dimensional parameters. The solution of the resulting coupled dimensionless differential equations with a constant coefficient describing the momentum, energy, and mass transfer equations was obtained by using the method of undetermine coefficient. The parameters embedded in the flow are thermal radiation , Prandtl number, entropy generation , Suction/injection parameter , heat source/sink , porous material . In addition, physical quantities of engineering interest such as the Bejan number , Brinkman number , volumetric flow rate , skin friction coefficient, and heat transfer rate were computed. It is noticed that velocity and temperature increase significantly with an increase in heat source and suction parameters, while a reverse trend is observed when heat sink and injection are present. It is also evident that, the heat source increases the temperature profile in the presence of injection parameter, and a reverse trend is observed when the heat sink increases in the presence of the suction parameter. skin friction is decreasing with increase higher values of porous material in both at when injection and , volume flow rate reduces with increasing values of heat source and shot-up with decreasing values of heat sink, its observed that entropy generation is increasing for higher values of ...........
