EFFECT OF CHEMICAL REACTION ON UNSTEADY MHD FREE CONVECTIVE FLOW PAST A SEMI-INFINITE VERTICAL POROUS PLATE WITH HEAT GENERATION

Abstract

This work is focused on the effects of variable viscosity and thermal conductivity on unsteady two-dimensional laminar flow of a viscous incompressible electrically conducting fluid past a semi-infinite vertical plate taking into account the chemical reaction with heat generation. The fluid viscosity is assumed to vary as a linear function of temperature. The governing equations for the flow are transformed into a system of non-linear ordinary differential equations are solved by a perturbation technique. The effects of the various parameters on the velocity, temperature, concentration, Skin friction number, Nusselt number and sheer wood number are computed in graphical and tabular form.
Keywords: Radiation parameter, Thermal conductivity, MHD, porous medium, viscosity and Heat generation.
