摘要

摘要: 基于边界积分法建立狭窄流域内气泡破裂数值模型，开发相应的计算程序，分别模拟对称破裂与非对称破裂两类典型工况并与相应实验结果进行对比，计算值与实验值吻合很好，表明三维数值模型的有效性．从狭窄流域内气泡运动的基本现象入手，基于开发的程序系统地研究气泡的对称破裂与非对称破裂，在已有数值研究成果和实验数据基础上，提出气泡破裂的可行性准则，研究分裂后子气泡的动力学特性，并分析距离参数对气泡破裂特性及子气泡动力学行为的影响，总结相应规律，旨在为相关气泡破裂特性研究提供参考．

Abstract: Based on boundary in tegral method,the 3D bubble breakup model in the narrow flow field was erected and corresponding computing program was developed to smiulate symmetrical and unsymm etrical bubble breakup.The calculated results are compared with the expermiental results and agree with them very well, which indicates the numerical model is valid. Starting with the basic behavior of bubble in the narrow flow field,the symmetrical and unsymmetrical bubble breakup was studied systematically with the program developed,and feasible rule of 3D bubble breakup was presented based on the published numerical results and experimental data.Besides,the dynamics of sub-bubbles after splitting was studied,and the influence of characteristic parameters on the bubble breakup and sub-bubbles dynamics was analyzed.
