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.

An analysis is made of the steady ow of a non-Newtonian uid past an inÿnite porous at plate subject to suction or blowing. The incompressible uid obeys Ostwald-de Waele power-law model. It is shown that steady solutions for velocity distribution exist only for a pseudoplastic (shear-thinning) uid for which the power-law index n satisÿes 0 ¡ n ¡ 1 provided that there is suction at the plate. Velocity at a point is found to increase with increase in n. No steady solution for velocity distribution exists when there is blowing at the plate. The solution of the energy equation governing temperature distribution in the ow of a pseudoplastic uid past an inÿnite porous plate subject to uniform suction reveals that temperature at a given point near the plate increases with n but further away, temperature decreases with increase in n. A novel result of the analysis is that both the skin-friction and the heat ux at the plate are independent of n.
