A computational study of super- and partial-cavitation over axisymmetric bodies is presented using two numerical methods. The first method is based on the VOF technique where the transient Navier-Stokes equations are solved along with an equation to track the cavity interface. The second method is that of the steady boundary element method (BEM) which is a model based on the potential flow theory. The supercavitation results of the two methods for disk and cone cavitators are compared with each other and with those of the available experiments and analytical relations. Two different geometries for a cone with various cone angles are considered. Also, the results of comparison between the two methods for partial cavitation over a sphere, a blunt cylinder, and a cylinder with a spherical head are presented.
