中文摘要：
进行了不同壳体约束条件下的液体爆炸抛撒实验,讨论了壳体对起爆后早期抛撒流场特征的影响,分析了爆炸分散过程中液体的状态变化和破碎分散机理,并通过数值模拟进行了对比分析。结果表明,在爆炸反射稀疏波的作用下液体发生空化现象,壳体强度越高,空化发生的延迟越大,发生位置越靠近爆心,同时,爆炸产物气体与液体在其界面附近越早发生掺混。
英文摘要：
In this study,experimental investigations on the liquid＇s explosive dispersal under different shell constraints were carried out,effects of shell constraints on the early characteristics of the flow field were discussed,and the mechanism for liquid state transition and breakup was analyzed and compared with the numerical simulation.The results show that cavitation occurs in the liquid when the rarefaction waves reflects on the shell.The stronger the shell constraint,the greater the delay of the cavitation that emerges and the closer to the center where the cavitation is located,and the earlier the explosive product mixes with the liquid on the nearby interfaces.
