Abstract
The Görtler series method for the solution of the two-dimensional boundary-layer flow equations is extended to include Ostwald—deWaele (power-law) fluids. The resulting differential equations are solved numerically for the first two to four terms of the series solution over a wide range of dilatant and pseudo-plastic behavior and for two different classes of flows, flat plate type flows and symmetrical flows over rounded contours. It is shown that the approximate method of Acrivos gives, in general, a good approximation to the velocity gradient at the wall, but that errors of 20 per cent or greater can be expected when using this method in the vicinity of the separation point or for highly pseudo-plastic fluids.
