Heat transfer effect on MHD flow of a micropolar fluid through porous medium with uniform heat source and radiation

Abstract

The present study examines the effect of heat transfer on electrically conducting MHD micropolar fluid flow along a semi-infinite horizontal plate with radiation and heat source. The uniform magnetic field has applied along the principal flow direction. The obtained governing equations have been converted into a set of dimensionless differential equations and then numerically solved by using a well-known Runge-Kutta method with shooting technique. The velocity, microrotation, and temperature distribution are presented for various physical parameters. The numerical values of skin friction and Nusselt numbers at the plates are shown in tabular form, and the obtained results are compared with the results of a previous study. It has been found that the magnetic parameter increases the velocity profile whereas the boundary layer thickness reduces due to the inclusion of coupling parameter and inertia effect. The presence/absence of magnetic parameter and coupling parameter enable to enhance the angular velocity profile while it is worth to note that the backflow has generated in the vicinity of the plate.

“…Aslani et al [16] discussed the micropolar Couette fluid flow with magnetic fields. Mishra et al [17] worked on the effect of magnetohydrodynamic outflow by using the micropolar fluids, keeping the medium porous. Nadeem et al [18] investigated heat flow of 3-D micropolar fluids with Riga plate.…”
