摘要
本文利用高速摄影技术(100,000幅/秒),在不同粘性液体中对电火花放电造成的空泡膨胀及压缩过程的观测表明:液体粘性对空泡历时、空泡半径,泡壁的速度及加速度等均有影响。并将其与理论计算结果进行了对比,得出了一些定性方面的成果。
Using the high speed photogtaph, obserations of the process of bubble expanding and shrinking as a result of electric spark discharge shown that h'quid viscosity has an obvious influence on the bubble time duration, size, velocity and acceleration, etc. Theoretical analysis and numerical calculation of the effect of h'quid viscousity on bubble expauding and shriking was compared with result of experiment.
