Steady two-dimensional oblique stagnation-point flow towards a stretching surface

Abstract

An analysis is made of steady two-dimensional oblique stagnation-point flow of an incompressible viscous fluid towards a surface which is stretched with a velocity proportional to the distance from a fixed point. It is found that for very small shear in the free stream, the flow has a boundary layer structure and the thickness of the boundary layer decreases with increase in straining motion near the stagnation region. It is also observed that the flow has an inverted boundary layer structure when the stretching velocity of the surface exceeds the stagnation velocity of the free stream. In this case, the surface shear stress decreases with increase in free stream stagnation velocity.
