Notwithstanding the effectiveness of ventilated cavitation as a safe way to accelerate and achieve natural supercavitation, detailed physics cavitating flows hydrodynamic effects on underwater vehicles have been rarely explored. The present work deals with computational investigation supercavitating around high-speed vehicle its characteristics. homogeneous mixture model is adopted for describi...

A practical cavitator design method for straight-running-type supercavitating torpedoes was developed in this paper. Design requirements were first drawn terms of torpedo performance characteristics, such as maximum range and motion stability. This determines the optimum satisfying that not only minimize total drag torpedo, extending range, but also provide hydrodynamic forces required straight...

The problem that is studied concerns a yawed wedge under a free surface, moving at a uniform speed. The model involves a trailing cavity whose boundary is a dividing streamline through the vertex of the wedge. The cavity closure mechanism is described according to the Tulin– Terent’ev single-spiral-vortex model. A closed-form solution to the governing nonlinear boundaryvalue problem is found by...

A simple method is formulated for predicting three-dimensional supercavitating flow behind cavitators subject to gravitational acceleration and motion of the cavitator. The method applies slenderbody theory in the context of matched asymptotic expansions to pose an inner problem for the cavity evolution downstream from the locus of cavity detachment. This inner problem is solved by means of a c...
