ABSTRACT:
In this paper nonlinear analysis is performed for studying the effect of couple stress forces on convective stability in a steady, viscous, incompressible fluid saturating a porous medium. The nonlinear analysis is carried out by using energy method and Galerkin technique is used to solve the obtained eigen value problem. The linear and nonlinear thresholds that encapsulate the physics of the onset of convection are found to be same. It is observed that the permeability of porous medium and magnetization parameter tends to destabilize the system whereas the couple stress and solute gradient is seen to have a stabilizing impact on the system.
