On the MHD flow and heat transfer of a micropolar fluid in a rectangular duct under the effects of the induced magnetic field and slip boundary conditions

摘要

The heat and mass transfer due to the steady laminar and incompressible micropolar fluid flow through a rectangularduct with the slip flow and convective boundary conditions are numerically calculated. The fluid moves under an externalmagnetic field applied on a plane perpendicular to the axis of the duct. The governing nonlinear partial differentialequations of momentum, microrotation, induction, and the energy are solved simultaneously by the finite differencemethod. The effect of various numbers and parameters such as Reynolds, magnetic Reynolds, Hartmann, coupling,Brinkman numbers, the slip flow and convective parameters are presented in graphs. Some comparisons with previousworks are included.
