• INFLUENCE OF TEMPERATURE-DEPENDENT VISCOSITY ON THE MHD COUETTE FLOW OF DUSTY COUPLE STRESS FLUID WITH HEAT TRANSFER

Abstract

This paper studied the effect of variable viscosity on the transient couette flow of dusty couple stress fluid with heat transfer between parallel plates. 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 upper plates are moving with a uniform velocity while the lower is kept stationary. The governing nonlinear partial differential equations are solved by transformation method.  (Hankel and Cosine transformation). some important effect for the variable viscosity and uniform magnetic field on the transient flow, couple stress fluid and heat transfer both the fluid and dust particle are studied.
