多重プロセス型モデルによる極低温キャビテーションの熱力学的効果の CFD 解析

抄録

We previously constructed a new cavitation model called “Multi-process Cavitation Model”, which takes the various elementary processes in cavitation into account, and farily good results were obtained for cold water cavitation while a poor result was done for a cryogenic cavitation with thermodynamic effect. In this paper, we revisited the application of this model thoroughout investigation of the model parameters. We conducted a cavitation simulation on single hydrofoil, and found that the appropriate modeling of expasion/shrinkage is rather more important than the evaporation/condensation rate that causes thermodynamic effect.
