...Yoshiki Yoshida; Hideaki Nanri; Kengo Kikuta; Yusuke Kazami; Yuka Iga; Toshiaki Ikohagi 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...

... to vaporize to sustain a cavity. Therefore, evaporative cooling effects are more pronounced and the temperature of the liquid in the immediate vicinity of the liquid-vapor interface is depressed below the free-stream temperature. Because of the strong variation of thermodynamic properties (mainly the vapor...

... are difficult to transpose and corresponding correlations have not been validated for inducers. The only available results on temperature depression within cavities on an inducer are indirect estimates obtained from a comparison of visualizations with and without a thermodynamic effect.

...Jean-Pierre Franc; Guillaume Boitel; Michel Riondet; Éric Janson; Pierre Ramina; Claude Rebattet The thermodynamic effect on a cavitating inducer is investigated from joint experiments in cold water and Refrigerant 114. The analysis is focused on leading edge cavitation and cavitation instabilities...

...Yoshiki Yoshida; Yoshifumi Sasao; Mitsuo Watanabe; Tomoyuki Hashimoto; Yuka Iga; Toshiaki Ikohagi 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...

...-pentanone, hereafter referred to as fluoroketone, exhibits a strong thermodynamic effect even under ambient conditions. Static pressures were measured at seven chordwise locations along the centerline of the hydrofoil suction side and on the test section wall immediately upstream of the hydrofoil. Frequency...

...Satoshi Watanabe; Tatsuya Hidaka; Hironori Horiguchi; Akinori Furukawa; Yoshinobu Tsujimoto The suction performance of turbopumps in cryogenic fluids is basically much better than that in cold water because of the thermodynamic effect of cavitation. However, it is not still clear how...

However, relationships between the thermodynamic effect and cavitation instabilities are still unknown. To investigate the influence of the thermodynamic...

...Yoshiki Yoshida; Kengo Kikuta; Satoshi Hasegawa; Mitsuru Shimagaki; Takashi Tokumasu For experimental investigations of the thermodynamic effect on a cavitating inducer, it is nesessary to observe the cavitation. However, visualizations of the cavitation are not so easy in cryogenic flow...

...Satoshi Watanabe; Tatsuya Hidaka; Hironori Horiguchi; Akinori Furukawa; Yoshinobu Tsujimoto It is well known that the suction performance of turbopumps in cryogenic fluids is much better than that in cold water because of the thermodynamic effect of cavitation. In the present study, an analytical...

...Piero Colonna; Paolo Silva The use of dense gases in many technological fields requires modern fluid dynamic solvers capable of treating the thermodynamic regions where the ideal gas approximation does not apply. Moreover, in some high molecular fluids, nonclassical fluid dynamic effects appearing...
