A classical theory for cavitation tests in vacuum tank has been used. According to two principles, the test procedure in vacuum tank and the prediction of cavitation features on prototype were obtained. However, by using these test results it can not make a reliable prediction of cavitation feature on prototype. It shows what should be the considerable reasons for the difficulties in comparison between the results of cavitation tests in vacuum tank and how to improve the cavitation tests under a condition of vacuum pressure.展开更多
