Abstract
The boundary integral method is formulated for the problem of the fully nonlinear, axisymmetric potential flow past a body of revolution. A model is devised for the exact formulation of the reentrant jet cavity closure condition. It is demonstrated that the solution obtained is essentially independent of the length selected for the jet. Results obtained using the reentrant jet cavity closure model are compared with those obtained using the Riabouchinsky-type cavity closure model used by Uhlman (1987, 1989) and with experimental results. The agreement between the two cavity closure models is seen to be excellent, with the Riabouchinsky wall results deviating only slightly at short cavity lengths. The agreement of the reentrant jet model with the experimental data is also excellent, although the addition of the viscous component of drag is seen to be required for cavitating cones of sufficiently small half-angle.
