A mathematical study on entropy analysis in MHD forced convective flow through a circular channel

Abstract

In this paper, we study the effect of the flow of a viscous incompressible fluid within a circular channel filled with a hyper porous medium saturated with a rarefied gas amid a transverse magnetic field, thermal radiation and uniform heat flux on the walls. The velocity and heat equations of the fluid flow are solved analytically using the Homotopy Analysis Method (HAM). Approximate analytical expressions are determined for the velocity and temperature profiles and these profiles together with the entropy generation rate are discussed graphically. The results are compared with the previous study and found to be in consensus.
