UNSTEADY FREE CONVECTION FLOW OF THIRD GRAD ELECTRICALLY CONDUCTING FLUID PAST AN INFINITE VERTICAL PLATE

Abstract

In this paper the problem of, unsteady, hydromagnatic free convective flow of viscous incompressible and electrically conducting third order fluids past in infinite vertical Porous plate in the presence of constant suction and heat absorbing sinks is considered. It is found that the velocity and temperature distribution equations are controlled by different dimensionless parameters, namely, Grashof number Gr, prandtl number pr, Eckert number Ec, sink strength s, material moduli and coecostic parameter α. An analytic solution for each of the velocity and the temperature distribution is obtained. The velocity and temperature distributions are shown graphically taking many cases of Gr, pr, Ec, s, and α.
