This research has investigated the above-mentioned process resulting in cavitation erosion step by step.

根据片状空腔的总体积转化为初始云空泡的总蒸汽量，需要知道片状空腔表面的蒸发速率，即汽液界面。因此，通过测量高温高压水中产生的片状空腔的温度分布来预测空腔表面的蒸发速率，其中蒸发的热力学效应更加明显。测量了云穴脱落的频率和云团的大小和形状。此外，还利用激光全息技术测量了空穴中气泡的数量和大小，并利用自行研制的空化冲击力传感器测量了云中空穴坍塌时的撞击力。同时拍摄了一段帧速率为40500fps的高速视频。在考虑撞击力时程的基础上，详细研究了云腔坍塌的行为。

In terms of the total volume of sheet cavity, which turns into the total vapor volume of initial cloud cavity, it is necessary to know evaporation rate at the sheet cavity surface which is vapor/liquid interface. Thus, the evaporation rate at cavity surface has been predicted by measuring the temperature distribution along a sheet cavity generated in high temperature and high pressure water where the thermodynamic effect due to evaporation appears more clearly.Using a high speed video, the whole cavity behavior has been observed in detail. The frequency of cloud cavity shedding and the size and shape of the clouds have been measured. Also, a laser holography technique has been applied to measure the number and size of the bubbles in a could cavity.Cavitation impact force sensors developed and fabricated by ourselves have been used to measure the impactive forces due to collapse of cloud cavities. A high speed video has been taken at the same time with frame rate of 40,500 fps. Behavior of cloud cavity collapse has been investigated in detail with correlation to the time history of the impact force taken into account.
