Abstract
The symmetric vortex separation that is observed on the leeward side of slender bodies of revolution at high angle of attack in the subsonic to moderately supersonic-velocity range is analyzed by means of the “lumped-vorticity” approximation suggested by Edwards and Hill. The equivalent unsteady two-dimensional problem of indicial motion of a cylinder in an incompressible fluid with symmetric vortex wake is also considered. Body vortex position and normal force per unit length are presented for a cylinder and a slender cone at high angle of attack and compared with available experimental information.
