Mixed convection unsteady stagnation point flow over a stretching sheet with heat transfer in the presence of variable free stream. (English) Zbl 1344.76079

Summary: An analysis is performed for the unsteady mixed convection flow of an incompressible viscous fluid at the stagnation point on a stretching sheet in the presence of a variable free stream. The equations of motion and energy are transformed into ordinary differential equations by using similarity transformations. Homotopy analysis method is used for the solution of the governing problem. The results have been discussed by plots. The presented values of the function are shown very close to the previous limiting solutions.
