Effect of the Couple-Stress on Micro Polar Rotating Fluid Flow Saturating a Porous Medium

Abstract

Effect of the couple-stress on micro polar rotating fluid layer heated from below in the presence of varying gravitational field in a porous medium is studied, using normal mode, the problem has been analyzed and it is found that the permeability has destabilizing effect. The rotation, couple-stress parameter and micro-polar parameters have stabilizing effect. The condition of over stability has been found
