This article reports a similarity solution and the Von Karman integral method for buoyancy-induced flow and heat and mass and mass flux from the wall is constant. Governing parameters for the problem are the buoyancy ratio N, Lewis number Le, thermal stratification parameter S2 and the solutal stratification parameter S2. Results for Nusselt and Sherwood numbers are presented for wide range of governing parameters, and it is observed that both these physical characteristics increase with S1 and S2. %8 2002-03-01
