    摘要:

    研究了振动空泡与明胶弹性壁面及管道的相互作用机理,其中振动空泡由一个60 V的低压电路产生,实验时采用高速相机记录振动空泡的形状变化及弹性壁面的膨胀与收缩过程,并且高速相机的帧率分别设为12 500 f/s和15 000 f/s。实验观察到了空泡分裂及二次空化现象,结果表明:振动空泡的动力学行为明显受到了弹性壁面的影响。

    Abstract:

    In this paper, the interaction between oscillating bubble and elastic wall was experimentally investigated. The oscillating bubble was generated by using a very low voltage of 60 V. The shape evolution of the bubble and the dilation of the elastic wall were recorded by a highspeed video camera, and the images were captured at a speed of 12 500 fps and 15 000 fps (i.e., frames per second). The bubble splitting and secondary cavitation phenomenon was observed in this experiment, and the experimental results showed that the dynamic behavior of the oscillating bubble was obviously influenced by the elastic wall.
