Effect of slip and magnetic field on composite systems

Abstract

The influence of slip velocity and transverse magnetic field on a horizontal composite (porous/ electrically conducting fluid) layer is investigated analytically and numerically. The analytical method is based on a perturbation technique while the numerical simulation is based on a finite difference scheme. Several important characteristics of the conducting flow as well as the concentration fields in the composite layer are reported. Also, the dependence of these characteristics on the dimensionless parameters of the problem are described graphically. The results of the present analysis are compared with similar results of viscous flow in the absence of a magnetic field and good agreement is found.
