Chemical reaction effects on MHD free convective flow past an inclined plate

Abstract

Aim of this paper is to investigate the chemical reaction effects on transient MHD free convective flow of a viscous incompressible electrically conducting fluid along an inclined isothermal non-conducting plate in the presence of transverse magnetic field and viscous dissipation.  The dimensionless governing equations are unsteady coupled and non-linear partial differential equations.  An analytic method fails to give a solution.  Hence an explicit finite difference scheme of DuFort - Frankel method, which is unconditionally stable is employed.  The effect of the chemical parameter (Kr), magnetic parameter (M), buoyancy ratio parameter (N), Schmidt number (Sc), Eckert number (Ec) on the velocity, temperature and concentration fields are extensively discussed with the help of graphs.
