Research Abstract |
Cavitation occurs inescapably in inlet of turbopump of liquid rocket engine, because the liquid oxygen and hydrogen turbopumps are downsized and made as high-horsepower to the utmost limit. The cavitation sometimes yields cavitation instability, which is undesirable oscillation of the pump induced by mutual interference between the unsteady characteristics of cavitation and the pump system. The cavitation instability induces the declaration of efficiency or damage in the pump. In the present study, in an effort to reuse of the liquid rocket, the numerical method for the cavitation instability and cavitation erosion is attempted to be develop especially in a cryogenic environment such as liquid hydrogen and oxygen.
