Cavity Drag in Two and Three Dimensions

Abstract

The free streamline theory has been applied to the computation of the cavity drag of symmetrical wedges of arbitrary angle. The drag coefficients and cavity widths and lengths are tabulated for a range of both cavitation parameter and internal angle. The pressure distributions computed for two-dimensional wedges have been taken to be approximately correct for cones of revolution of the corresponding internal angles. Under this assumption, drag coefficients for right circular cones of arbitrary internal angle have been computed and are tabulated for a range of both cavitation parameter and internal angle.
