Development of Cavitation Suppression Using Thermal Characteristics of Insoluble Mixture Liquid

本研究的目的是用制冷剂液体抑制高脉冲力对空化塌陷运动的抑制。对单个气泡在不同压力场中的径向运动和空化流动进行了高速摄像机的可视化和冲击力的测量。尽管有制冷剂的空化流动中气泡的生长和气泡的生成量大于无制冷剂的空化流动，但有制冷剂时的脉冲力比无制冷剂时的脉冲力受到抑制。

The aim of this study is a high impulsive force suppression with refrigerant liquid on cavitation collapse motion. The visualization with a high-speed video camera and a measuring of impulsive force was performed for both experiments of a single bubble radial motion in varying pressure fields and cavitating flow. The impulsive force with refrigerant liquid was suppressed compared with the case without refrigerant it, though the bubble growth and amount of bubble generation in cavitating flow with refrigerant liquid was greater than that of without case.
