The aim of this work is to study Soret and chemical reaction
effects on laminar mixed convection boundary layer flow, heat and
mass transfer past a semi-infinite horizontal flat plate in the presence
of heat generation. A transformation is introduced, which reduces
the equations governing the flow to a system of non-linear coupled
ordinary differential equations. The transformed equations are solved
numerically using the fourth order Runge-Kutta integration scheme
coupled with the shooting method. Graphical results for the velocity,
temperature and concentration profiles for various parametric conditions
are presented and studied. The effect of the chemical reaction
parameter, Soret parameter and the heat generation parameter on the
local skin-friction coefficient, the local Nusselt number and the local
Sherwood number are presented in tabular form and discussed.
