A Study Of Radiation And Mass Transfer Effects On Unsteady Mhd Free Convective Fluid Flow Embedded In A Porous Medium With Heat Generation/Absorption

An analysis has been done for unsteady, two dimensional, hydro magnetic, laminar boundary layer flow of a viscous in compressible electrically conducting fluid along a vertical plate in the presence of thermal and buoyancy effects. The dimensionless governing equations of the flow are solved analytically by an efficient Galerkin finite element method. Nusset number and Sherwood number are present and discussed. It has been found that thermal conductivity and concentration buoyancy effects shows linear variation where as the fluid velocity varies with temperature. The effect with variation of the parameters Pr,Sc,M,Q,K has been investigated with the help of graphs.
