MHD naturel convection flow of a couple stress fluid in a porous vertical channel

Abstract

The effects of the couple-stress parameter only or combined with Darcy/Forchheimer numbers are studied for natural convection of mass and heat transfer, of a couple stress fluid through a porous channel in the presence of a magnetic field. To obtain easy ordinary system, similarity transformations are used for the nonlinear partial differential equations. Then the resulting equations are numerically solved. Graphical illustrations containing non-dimensional velocity, temperature, and concentration are presented mainly for different values of the couple-stress parameter via the large values of the Darcy and Forchheimer numbers
