| Abstract: | In this paper, the relation of cavitator profile and supercavity shape and the drag characteristics are numerically simulated by a commercial CFD software Fluent 6.0. The factors effecting drag reduction of navigation object in supercavity and the way to control supercavity shape to reduce drag are analyzed in detail, which offers preliminary theoretical foundation to optimize the shape of supercavity. The experimental and numerical simulation results are fit quite well. |
