EFFECTS OF SLIP FACTORS ON THE UNSTEADY STAGNATION POINT FLOW AND HEAT TRANSFER TOWARDS A STRETCHING SHEET: AN ANALYTICAL STUDY

摘要

This paper aims at presenting an analytical solution to the problem of unsteady stagnation-point flow and heat transfer towards a stretching sheet. The homotopy analysis method (HAM) is employed to compute the solution of the system of nonlinear equations governing the problem. The slip contributions, which appeared in the solution as expected, tend to zero when the parameters λ and δ tend to zero. Finally, the influence of the material, slip, and the unsteadiness parameters of the fluid motion, as well as a comparison with the numerical solution are also discussed with the aid of graphical illustrations.
