Brinkman Model for Unsteady MHD Free Convection Flow of a Chemical Reacting Doubly Stratified Fluid with Heat Generation and Radiation

Abstract

In this investigation, the effects of magneto-hydrodynamics, heat generation and thermal radiation have been discussed on unsteady natural convection flow in a Brinkman porous medium saturated with a chemically reacting doubly stratified fluid. Initially, the flow is described through time-dependent differential equations. These are converted into a set of coupled nondimensional differential equations. Crank-Nicolson type scheme is employed to analyze the solution of the model. In order to analyze the usefulness of the investigation the dimensionless local skin-friction, heat and mass transfer rates have been presented graphically for different combinations of flow governing parameters.
