The problem of combined free-forced convection and mass transfer flow over a vertical porous flat plate, in presence of heat gene ration and thermal- diffusion, is studied numerically. The non-linear partial differential equations and their boundary conditions, describing the problem under consideration, are transformed into a system of ordinary differential equatio ns by using usual similarity transformations. This system is solved numerically by applying Nachtsheim-Swigert shooting iteration technique together with Runge-Kutta sixth order integration scheme. The effects of suction parameter, heat generation parameter and Soret number are examined on the flow field of a hy drogen-air mixture as a non-chemical reacting fluid pair. The analysis o f the obtained results showed that the flow field is significantly influenced b y these parameters.
