Hall Current Effects on Free Convection Casson Fluid Flow in a Rotating System with Convective Boundary Conditions and Constant Heat Source

Abstract

In this paper we investigated an unsteady free convection flow of casson fluid bounded by a moving vertical flat plate in a rotating system with convective boundary conditions. The governing equations are solved analytically by using perturbation technique. Finally the effects of various dimensionless parameters like inclined angle, Casson parameter, Heat source and Suction parameter on velocity, temperature, friction factor and local Nusselt number are discussed with the help of graphs and tables. Through this study, it is found that increasing values of casson parameter reduces the velocity and increase in inclined magnetic field or hall current parameter enhances the velocity profiles.
