内容記述 | Cavitation in cryogenic fluids, e.g., propellants of rocket engines, has a thermodynamic effect because of thermal imbalance around the cavity. The thermodynamic effect on cavitation is beneficial in that it improves cavitation performances due to the delay of cavity growth. In the present work, two experiments were conducted on a three-bladed cavitating inducer in which liquid nitrogen and cold water as working flow were used in order to confirm the thermal effects. Aspects of the cavitation in the inducer were observed by direct optical visualization both in liquid nitrogen and water. The bubbles of the tip vortex cavitation were very fine, and the thickness of the cavitation on the blade surface was very thin in liquid nitrogen compared with those in cold water. The growth of the cavity length along the blade was much suppressed as decrease the cavitation numbers in liquid nitrogen. | |||||
