BOUNDARY-LAYER FLOW OF POWER-LAW FLUIDS PAST ARBITRARY PROFILES

Two-dimensional steady-state boundary layer equations of power-law flu ids are derived using a special coordinate system which makes the equa tions independent of the body shape immersed in the flow. In deriving the boundary layer equations, the method ot matched asymptotic expansi ons is used. It is shown that the similarity solutions for power-law f luids are much the same as those of Newtonian fluids. Similarity solut ions corresponding to the case of parallel flow past a flat plate and stagnation-point flow are presented. Finally, the shear stress is calc ulated for different geometries.
