Investigation of free convection in micropolar nanofluid with induced magnetic field

Abstract

The spotlight of the study is mainly the effect of the induced magnetic field on the free convection for a non-Newtonian micropolar nanofluid using the single phase model. The nondimensional equations describing the fluid motion, energy, angular momentum and the induced magnetic field of nanofluid are solved using the Keller box method. The study of the effect of the magnetic Reynolds number on the fluid flow, heat and mass transfer is carried out as an important part of the investigation. The behavior of the nanofluid is also observed under the effect of the spin viscosity material parameter of the micropolar fluid. It is interesting to see that the angular momentum boundary layer shrinks for a greater Prandtl number while the suction velocity enhances the angular momentum profile. The material parameter is found to reduce the velocity profile as well as the skin friction coefficient.
