This study reports the approximate analytical modeling of heat and mass transfer in hydromagnetic flow over a non-isothermal stretched surface, incorporating the effects of heat generation/absorption and transpiration. Homotopy analysis method (HAM) is used to obtain the analytical solutions of the non-linear governing equations. The effects of several parameters (suction/injection parameter f(w), magnetic parameter M, heat source/sink coefficient epsilon, Prandtl number Pr, Schmidt numberSc, and velocity and temperature power-law parameters m, n) on the dimensionless velocity, temperature, concentration, skin friction, and Nusselt and Sherwood numbers are investigated. The results of the local skin friction coefficient and reduced heat transfer rate are compared with the published data for a special case and found to be in good agreement. It is found that the reduced Nusselt and Sherwood numbers are increasing functions off.
