| 摘 要： | 为研究近水面水下爆炸产生的水柱效应,对水面下2m处2kg TNT炸药爆炸水柱效应进行了理论计算和试验研究,并运用MSC.DYTRAN和PAM-FLOW两种软件进行了数值模拟. 结果表明,水柱上升高度历时曲线呈开口向下抛物线形状,水柱上升速度近似呈指数衰减;爆炸后水柱形成过程数值模拟云图与试验结果吻合.

| Abstract: | Water column produced by near water surface explosion is an important topic of study and simulations based on its theory and experiment has great significance.An effective method to solve such problems is suggested.Program MSC.DYTRAN and program PAM-FLOW were introduced in the calculation for 2 m underwater explosion with 2 kg of TNT.They deal with the problem about shock wave impacting the interface of the liquid and air.The result fits the theory and the experiment well.Underwater explosion of TNT calcula... |
