摘要
基于VOF模型,借助FLUENT软件,对初始位置不同、大小不同的2个气泡进行了数值模拟,主要研究气泡在上升过程变形、融合、破裂等现象,分析气泡上升过程中的尾迹流,揭示了水平和竖直2个气泡相互吸引、排斥等现象,分析了2个气泡速度场相互影响。研究表明,气泡间距越小,速度场相互影响越大,气泡越容易相互吸引、融合。
Based on the model of VOF,numerical simulation of two bubbles rising with different position and size is carried out by using FLUENT software. The deformation,fusion,fracture process and the wake flow of rising bubbles are calculated. The phenomena of mutual attraction and repulsion between two horizontal and vertical bubbles are given respectively. The influence of two rising bubbles on the velocity field is analyzed. The smaller the distance between two bubbles is,the greater the influence of two rising bubbles on the velocity field is,the more easily the phenomenon of mutual attraction and fusion appears.
