Toshiya Kimura, Auteur ; Yoshida, Yoshiki, Auteur ; Tomoyuki Hashimoto, Auteur |Unsteady cavitation phenomena such as rotating cavitation and cavitation surge are often observed in a turbopump inducer of a rocket engine, sometimes causing undesirable oscillation of the system. Investigation of their mechanism and prediction[...]

Yoshida, Yoshiki, Auteur ; Masato Eguchi, Auteur ; Taiichi Motomura, Auteur |Asymmetric cavitation, in which cavity lengths are unequal on each blade, is known as a source of cavitation induced shaft vibration in turbomachinery. To investigate the relationship of the uneven cavity length and rotordynamic force in a cavit[...]

Kengo Kikuta, Auteur ; Yoshida, Yoshiki, Auteur ; Mitsuo Watanabe, Auteur |Based on the length of the tip cavitation as an indication of cavitation, we focused on the effect of thermodynamics on cavitation performances and cavitation instabilities in an inducer. Comparison of the tip cavity length in liquid nitrogen (7[...]

Yoshida, Yoshiki, Auteur ; Yoshifumi Sasao, Auteur ; Mitsuo Watanabe, Auteur |Cavitation in cryogenic fluids has a thermodynamic effect because of the thermal imbalance around the cavity. It improves cavitation performances in turbomachines due to the delay of cavity growth. The relationship between the thermodynamic effe[...]

Yoshida, Yoshiki, Auteur ; Hideaki Nanri, Auteur ; Kengo Kikuta, Auteur |The relationship between the thermodynamic effect and subsynchronous rotating cavitation was investigated with a focus on cavity fluctuations. Experiments on a three-bladed inducer were conducted with liquid nitrogen at different temperatures (7[...]
