ABSTRACT: Unsteady electromagnetic free convection flows of two-dimensional micropolar
fluid through in a porous medium parallel to a vertical porous plate have been investigated
numerically. Similarity analysis has been used to transform the governing equations
into its non-dimensional form by using the explicit finite difference method to
obtain numerical solutions. Estimated results have been gained for various values
of Prandtl number, Grashof number, material parameters, micropolar parameter, electric
conductivity, electric permeability, thermal relaxation time and the permeability
of the porous medium. The effects of pertinent parameters on the velocity, electric induction, magnetic induction,
microrotation and temperature distributions have been investigated briefly and illustrated graphically.
