Abstract

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.
