Research Abstract |
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.
