Abstract : A set of incompressible boundary-layer equations is derived which include second-order 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 boundary-layer 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)
