Abstract
In recent years, the maturity of the technology for a high speed underwater vehicle using supercavitation increase, it is entering the stage of applied research for practical use. In this study, hydrodynamic performance of the supercavitating object was evaluated by using a Viscous-Potential based Boundary Element Method(VP-BEM). 27 models with different shape parameters such as body diameter, length and fore-body shape were considered. The process of the supercavity development of each model was simulated, and drag generated according to operating conditions such as changes in water depth was analyzed.
