Abstract

The study of free convective MHD Couette flow of nanofluid between a vertical permeable channel is investigated in the prsence of thermal radiation effect and suction/injection through porous medium. Cu-ethyleneglycol is considered for analysis. Crank-Nicolson implicit diference method is used to solve system of governing unsteady, coupled equations. Also the flow and heat transfer for steady state of this mathematical model is also investigated. A comparetive study for both the cases steady and unsteady is analyzed and disscussed. For both the cases, effect of various physical parameters on velocity distribution, temperature distrtibuiton is depicted graphically.
