MHD Flow and Heat Transfer of Immiscible Micropolar and Newtonian Fluids Through a Pipe: A Numerical Approach

Abstract

This study deals with the MHD steady flow and heat transfer of micropolar and Newtonian fluids, flowing immiscibly through a circular pipe. The pipe is assumed to be filled with uniform porous media. The micropolar and Newtonian fluids occupy core and peripheral regions, respectively. The equations governing the flow are coupled and non-linear. The solutions for velocity, microrotation and temperature are acquired numerically employing finite difference method. At fluid–fluid interface, continuity of velocities, shear stresses, temperatures and heat fluxes are considered. The results for velocity, microrotation and temperature are displayed graphically.
