A method to predict the symmetric and asymmetric vortex shedding from circular and noncircular bodies at angles of attack and roll is presented. The three-dimensional steady flow problem is reduced to the two-dimensional, unsteady, separated flow problem for solution, and the resulting wake is represented by a number of discrete vortices. Conformal transformation of a noncircular cross section to a circular cross section requires analytical or numerical procedures which are also described. Comparisons of measured and predicted surface pressure distributions, flow field velocity surveys, and aerodynamic characteristics are presented for a variety of body shapes. (Kursetz)
