| 摘 要： | 为了研究通气流量对超空泡生成和溃灭的影响,在西北工业大学高速水洞实验室进行了系列通气超空泡生成和渍灭特征的试验.结果表明:空泡生成过程中,空泡长度和直径的变化特性与空泡溃灭时的变化特性相反;通气流量对空泡生成和溃灭均有较大影响,数据显示通气量对空泡生成的影响大于对空泡溃灭的影响.此研究为进一步研究超空泡的快速稳定生成提供了实验基础.

| Abstract: | In order to obtain the characteristics of ventilated supercavition formation and collapse,a series of experiments is executed in the NWPU high-speed water tunnel.The results indicate that the changes characteristics of cavity length and diameter are opposite to the supercavition collapse in the process of supercavition generation.The ventilation rate has greatly influence on supercavition generation and collapses,the data show that the influence of ventilation rate on supercavition generation is more signif... |
