| 摘 要： | 针对水中装药爆炸直达冲击波在自由面反射形成表面空穴的问题,应用水中爆炸冲击波声学近似理论,认为冲击波不能穿过空穴传播,得出一维水中爆炸表面空穴范围、水质点运动速度、水层抛射速度、空穴闭合时间以及空穴闭合产生的压力峰值与持续时间等,并将结论扩展到二维空间.通过具体算例,对比本方法与F.A.Costanzo等采用Arons...

| Abstract: | The present study is aimed at the problem of bulk cavitation from underwater explosion.Based on the theory of acoustic approximation and considered that the reflected rarefactive wave can not spread through bulk catvitation,the onset and termination depth of bulk cavitaion,the water particle velocity at various initial depth,the water spall velocity,the spall closure depth,the spall closure time,the peak pressure and the duration have been obtained in one-dimension and two-dimensions.The contrast between th... |
