| Abstract: | In oreder to investigate the characters of shape of ventilated supercavity and form drag of vehicles with various afterbodies, numerical investigation of ventilated supercavity vehicles has been conducted using the commercial CFD software Fluent6.0. The law of form drag coefficient of ventilated supercavity vehicles and shape of supercavity with various afterbodies was acquired. The dependence of form drag coefficient of ventilated supercavity vehicles and shape of supercavity on velocity and ventilation pressure was also obtained. This paper will guide experimental investigation of ventilated supercavity vehicles with various afterbodies. |
