非球形水下爆炸气泡坍塌机制
On the Mechanism of Non-spherical Underwater Explosion Bubble Collapse
摘要
Abstract
Experiment and simulation of cylindrical charge underwater explosion bubble motion has been conducted to investigate the collapse mechanism of non-spherical bubble and the behavior of its jet. The experimental results were compared against the numerical results for different configurations of charge. Results show that jet generated by a non-spherical bubble behaves different from that of a spherical bubble,which could be attributed to the variance of radius of curvature on the bubble interface. The collapse time for an initial bubble surface with bigger radius of curvature is earlier than that with smaller radius of curvature. As a result,the water jet may exhibit an asymmetric form.关键词
