Abstract

The effect of chemical reaction on free convection heat and mass trans fer for non-New tonian power law fluid overa vertical flat plate embedded in a fluid saturated porous medium was studied in the presence of yield stress and Soreteffect. The governing boundary layer equations and boundary conditions were cast in to a dimension less form by smiilarity tran sformations and the resulting system of equations was solved by a finite difference method. Results are presented and discussed for concentration profiles, as well as the Nusselt and Sherwood numbers for various values of the parameters, which govern the problem. The results obtained show that the flow field is in fluenced appreciably by the presence of chemical reaction parameter, order of chemical reaction parameterm, Soret number S_r, buoyancy ratio N, Lew is number Le, and dmiension less rheological parameter.
