Abstract

Homotopy analysis method (HAM) is applied to analyze the Soret and Dufour effects on the stagnation point flow over a stretching sheet in the presence of variable free stream. The resulting partial differential equations are converted into the ordinary differential equations. Skin friction coefficient, Nusselt and Sherwood numbers are also computed. Graphical results for dimensionless velocity, temperature and concentration fields are reported and examined for some parameters showing the interesting aspects of the obtained solutions.
