Abstract: “The present paper is to investigate the combined effects of the heat and mass transfer on the unsteady two-dimensional boundary layer flow over a nonlinear stretching sheet in the presence of Stagnation point and Suction/ Injection.The governing nonlinear partial differential equations have been reduced to the coupled nonlinear ordinary differential equations by the similarity transformations. The resulting equations are solved numerically by using Keller box method. The velocity, temperature and concentration distributions are discussed numerically and presented through graphs.”
