Abstract

Abstract: This study investigates the features of Hall current and thermophysical properties (viscosity, density and thermal conductivity) on unsteady, compressible, laminar flow of viscous fluid. Swirl flow is perceived by oscillatory movement of revolving disk. The well suited variables are adapted in order to achieve the non-similar system of expressions. The non-similar solutions are worked out numerically through scheme of finite differences and then utilizing Successive over Relaxation (SOR) technique. Physical parameters are discussed through one, two and three dimensional graphical forms. Tabular description of the resulting quantities is also formulated. The oscillatory thermal traces enhanced corresponding to increased magnetic parameter. An enhancement in Prandtl number contributes to lower down the thermal field but improves the rate of heat transportation.
