MHD free convection flow of a non-Newtonian power-law fluid over a vertical plate with suction effects

E. Mahmoudpour Molaei, F. Rouzbahani

Abstract


In this study, we present a numerical analysis of free convection flow and heat transfer is
presented for non-Newtonian power-law fluids with MHD effects over a vertical porous plate,
the surface of which is exposed to a constant wall temperature. For analysis, the Continuty,
Momentum and Energy equations are solved by the implicit finite difference scheme of
Crank–Nicolson’s type. Velocity and temperature of the flow have been presented for various
parameters such as Prandtl number, flow behavior index (n), porous plate parameter and
magnetic parameter. The local Nusselt number and skin friction coefficient is also presented
graphically.

Keywords: Magnetohydrodynamic flow; free convection flow; Non-Newtonian power-law
fluids; Vertical porous plate.
