| 摘 要： | 基于流体动力学理论分析了水下爆炸引起水质点速度与压力的关系式,提出水质点流速由瞬时流与滞后流组成,利用水下爆炸自由场压力实测数据的分析了瞬时流与滞后流的空间和时间分布。瞬时流传播距离远但强度小,滞后流强度高但传播距离小,3倍气泡半径内即降至1%。

| Abstract: | The concept of the transient flow is advanced based on the fluid dynamics theory.The transient flow and the after flow constitute the fluid particle flow due to underwater explosion together.The fluid particle flow space and time distributed characteristics are analyzed using underwater explosion test data.The transient flow transmission distance is long but intensity is weak.The after flow intensity is high but transmission is near,drop to 1% within 3 times of bubble radius. |

| Keywords: | underwater explosion after flow transient flow |
