Abstract

This paper concerns with scaling group analysis on MHD free convective heat and mass transfer over stretching surface considering effects of thermal-diffusion and diffusion-thermo with suction /injection, heat source/sink and chemical reaction by taking into account viscous dissipation. Scaling group transformations are used to convert the partial differential equations of governing equations into ordinary differential equation and are solved numerically by Keller Box Method. Numerical results obtained for different parameters are drawn graphically and their effects on velocity, temperature and concentration profiles are discussed and shown graphically. Skin-friction coefficient, Nusselt number and Sherwood number are presented in table. It is noted that the skin-friction coefficient and mass transfer gradient decrease with the increase of Prandtl number but the temperature gradient increases. The effect of Eckert number and heat source parameter increases the skin-friction coefficient and the mass transfer gradient but decreases the temperature gradient.
