| Abstract: | Based on many documents at home and abroad and a series of ventilated supercavity experiments conducted in water tunnel, some problems in experimental study of ventilated supercavity are summarized and discussed. The main contents include the similarity criteria in ventilated supercavity test, the influential law of gravity on ventilated cavity flow, closure and gas leakage problem of ventilated supercavity and mechanism of ventilated cavity instability. Finally, prospect of testing research topics of ventilated supercavity is suggested. |
