To investigate the effect of PSD on acoustic cavitation surge in turbopump, we conducted analyses with the resistance of PSD as a parameter. Consequently, we found that patterns of the acoustic cavitation surge were classified into three types by the

Rotordynamic fluid forces coupled with flow instabilities (i.e., impeller/diffuser rotating stall and rotating cavitation) in turbomachines were examined. Variations of fluid forces arisen from the flow instabilities have the similar characteristics,

Cavitation is physically "a vaporization of liquid" which needs latent heat for phase change. A cavity grows in the liquid, so the latent heat of vaporization can only be supplied by the liquid surrounding the cavity. Thus, the liquid close to the in

The cavitation surge is a kind of instability phenomenon generated in a liquid rocket engine, and it is known that when the inlet pressure of the turbopump of the engine is decreased, the frequency of cavitation surge continuously varied. On the othe
