Comparison of the length of tip cavity in liquid nitrogen (76 K and 80 K) with that in cold water (296 K) allowed us to estimate the strength of the thermodynamic effect. In addition, unstable cavitation phenomena occur when the cavity length develops over the throat. Sub-synchronous rotating cavitation appears both in liquid nitrogen and in cold water. In contrast, cavitation surge appears only in cold water at a lower cavitation number. From these experimental results, thermodynamic effects on cavitation performance and instabilities were discussed., 資料番号: AA0063226000, レポート番号: JAXA-RM-06-003}, title = {熱力学的効果がインデューサの吸込み性能とキャビテーション不安定に与える影響}, year = {2006} }
