中文摘要:

在一个狭窄的试管的一个水泡的生长,扩大和倒塌用实验和数字模拟被学习。在实验,水泡被一朵电的火花在一辆水坦克产生并且由一个高速度的照相机系统记录了。在数字模拟,水泡的进化被采用 axisymmetric 边界积分方程解决,就表面紧张效果而言。实验和数字模拟的结果被比较,好协议被完成。他们俩显示出那一相反喷气在倒塌阶段的结束形成并且渗透水泡,在一个戒指类型水泡前形式。由于 Bjerknes 在试管的吸引力下面围力量,一口戒指喷气被产生,向试管指。根据这,象试管墙和动能上的压力一样的一些物理数量在案例研究被计算。水泡行为上的试管直径和试管长度的效果也被调查。

英文摘要:

The growth, expansion and collapse of a bubble in a narrow tube are studied using both experiments and numerical simulations. In experiment, the bubble is generated by an electric spark in a water tank and recorded by a highspeed camera system. In numerical simulation, the evolution of the bubble is solved by adopting axisymmetric boundary integral equation, considering the surface tension effect. The results of experiments and numerical simulations are compared and good agreements are achieved. Both of them show that a counter-jet forms and penetrates the bubble at the end of the collapse stage, before a ring type bubble forms. Under the attraction of the tube wall due to Bjerknes force, a ring jet is generated, pointing towards the tube. On the basis of this, some physical quantities like the pressure on the tube wall and kinetic energy are calculated in a case study. The effects of tube diameters and tube lengths on the bubble's behaviors are also investigated.
