Slip-flow boundary conditions for non-Newtonian lubrication layers

The effect of a thin lubricating film of a power-law fluid between a bulk flow and a solid surface can be accommodated by a new slip-flow boundary condition. The applicability ifthis condition in boundary layer theory is explored and numerical similarity solutions are presented for plane stagnation-point flow. The amount of velocity slip is controlled by a si ngle dimensionless lubrication constant.
