The volume-acceleration model was introduced to determine the initial condition for bubble motion of underwater explosion. From the basic phenomenon of the interaction between bubble and rigid wall, the dynamic behavior of bubble near wall, including ring rebound of bubble and jet flow, was simulated and analyzed using MSC. DYTRAN finite element analysis software with developed subroutine defining the initial value and boundary condition of fluid field. The computational result of the behavior of bubble was compared with the experimental result. The comparison of results show that the former is consistent with the latter. The dynamic behavior of bubble near rigid wall and velocity of jet flow were studied systematically. It is summarized that the dynamic behavior near bottom rigid wall is close relevant to depth and distance. The research is of value to relevant theory modelings and engineering calculations.

采用体积加速度模型确定水下爆炸气泡运动的初始条件,基于MSC. DYTRAN有限元软件开发了定义流场初始条件和边界条件的子程序,对气泡在水平刚性壁面附近的运动特性进行了数值模拟,通过对比发现数值计算结果与实验结果具有较好的一致性,证明了初始条件定义、子程序开发和有限元模型建立的正确性和数值计算的准确性。以此为基础,研究了水深、泡心与刚性底面之间的距离对气泡动态特性和射流速度的影响,通过数值计算得到了一些有规律的曲线。计算模型、方法及结果对相关的工程研究和计算具有一定的参考价值。

采用体积加速度模型确定水下爆炸气泡运动的初始条件,基于MSC. DYTRAN有限元软件开发了定义流场初始条件和边界条件的子程序,对气泡在水平刚性壁面附近的运动特性进行了数值模拟,通过对比发现数值计算结果与实验结果具有较好的一致性,证明了初始条件定义、子程序开发和有限元模型建立的正确性和数值计算的准确性。以此为基础,研究了水深、泡心与刚性底面之间的距离对气泡动态特性和射流速度的影响,通过数值计算得到了一些有规律的曲线。计算模型、方法及结果对相关的工程研究和计算具有一定的参考价值。

The volume-acceleration model was introduced to determine the initial condition for bubble motion of underwater explosion. From the basic phenomenon of the interaction between bubble and rigid wall, the dynamic behavior of bubble near wall, including ring rebound of bubble and jet flow, was simulated and analyzed using MSC. DYTRAN finite element analysis software with developed subroutine defining the initial value and boundary condition of fluid field. The computational result of the behavior of bubble was compared with the experimental result. The comparison of results show that the former is consistent with the latter. The dynamic behavior of bubble near rigid wall and velocity of jet flow were studied systematically. It is summarized that the dynamic behavior near bottom rigid wall is close relevant to depth and distance. The research is of value to relevant theory modelings and engineering calculations.
