Abstract

This article is on a study of the behavior of MHD flow and heat transfer in the presence of heat source and chemical reaction over a flat plate. The steady two dimensional partial differential governing equations are transformed using standard dimensionless variables resulting in a coupled nonlinear ordinary differential equation with some embedded parameters. The Homotopy Perturbation Method (HPM) is employed to solve the system of dimensionless equations and the approximate analytical solutions obtained are further analyzed using MAPLE 17 symbolic platform. It is observed that the flow velocity within the boundary layer decreases with increasing magnetic field. Further parametric analysis shows that the temperature increases with increasing Hartmann number while it decreases with increasing Prandtl number. Further observation reveals that temperature profile increases rapidly with increasing heat source and chemical reaction parameters while the concentration profile decreases with increasing heat source and chemical reaction parameters. Graphical demonstrations of these solutions shed more lights on the behavior of the system.
