Symmetric, Rotational, Supercavitating Flow About a Slender Wedge

Abstract

Two approximations to the linearized theory for supercavitating flow about slender bodies are applied to the case of a symmetric, rotational flow about a slender wedge. Both approximations produce relationships for the cavity length and drag coefficients; one approximation also gives certain nonunique solutions not encountered in the corresponding irrotational flow. The presence of rotation is shown to create significant changes in the length of the trailing cavity, but small changes in the drag coefficient.
