内容記述 | Synchronous rotating cavitation is one type of cavitation instability, causing synchronous shaft vibration or head loss. On the other hand, cavitation in cryogenic fluids has a thermodynamic effect on cavitating inducers because of thermal imbalance around the cavity. To investigate the influence of the thermodynamic effect on synchronous rotating cavitation, we conducted experiments in which liquid nitrogen was set at different temperatures (74 K, 78 K and 83 K). We clarified the thermodynamic effect on synchronous rotating cavitation in terms of cavity length, fluid force, and liquid temperature. Synchronous rotating cavitation occurs at the critical cavity length of L(sub c)/h = 0.8, and the onset cavitation number shifts to a lower level due to the suppression of cavity growth by the thermodynamic effect, the influence of which becomes more significant with rising liquid temperature. Furthermore, we confirmed that the fluid force acting on the inducer increases markedly under conditions of synchronous rotating cavitation. | |||||
