Abstract : A set of incompressible boundarylayer equations is derived which include secondorder curvature effects. These equations are used to analyze flows past spheres and ellipsoids without surface suction or injection to determine the effect of the curvature terms on boundarylayer properties near separation. Finally the suction velocity necessary to maintain a particular value of constant displacement thickness on a sphere is determined. It appears that infinite suction is required as the rear stagnation point of the sphere is approaches. (Author)
