水下爆炸气泡融合动态特性研究

在自然界中，气泡融合是一种重要的物理现象．基于势流理论，采用边界积分法，对水下爆炸气泡融合进行数值模拟研究．依据已有的数值研究成果和实验数据，建立气泡融合三维动力学数值模型，数值模拟结果与实验值吻合良好．应用该文开发的三维计算程序，分析距离、水深等特征参数对气泡融合动态特性的影响，得到了一些规律性的曲线和结论，旨在为水下爆炸气泡融合机理和动态特性研究提供理论参考．

Study on Fusion Dynamics of Underwater Explosion Bubbles

Fusion phenomenon of bubbles is common and significant in nature.Potential flow theory and boundary integral method were employed to simulate the fusion of underwater explosion bubbles.According to the numerical results and experimental data from published works,three-dimensional model of fusion bubble was established.Comparing the numerical results with experimental data,well coincidence was presented.Influences of characteristic parameters involved,such as distance,depth and so on,were especially investig...
