Effect Of Variable Viscosity On Transient Flow Of Adusty Conducting Fluid In A Parallel-plates Channelrnwith Uniform Suction And Injection

摘要

This paper studies the effect of temperature dependent viscosity on unsteady magnetohydrodynamic (MHD) flow of dusty conducting fluid in a parallel-plates channel with uniform suction and injection. The fluid is acted upon by a constant pressure gradient and an external uniform magnetic field is applied perpendicular to the plates. The parallel plates are assumed to be porous and subjected to a uniform suction from above and injection from below. The viscosity of the fluid is assumed to vary exponentially with temperature. The governing nonlinear partial differential equations are solved numerically and some important effects for the variable viscosity and the uniform magnetic field on the transient flow and heat transfer of both the fluid and dust particles are indicated.
