US-Germany Cooperative Research: Noise, Vibration and Erosion Due to Partial Cavitation

9905631Arndt该奖项支持明尼苏达大学双城分校的Roger Arndt与位于德国奥伯纳赫的慕尼黑工业大学奥斯卡·冯·米勒研究所的Andreas Keller合作。该项目将重点研究水翼后缘周期性云空化的形成。泵、水轮机和船用推进器必须经常在压力较低的空化状态下工作，导致气泡形成，这可能会损坏机器内部部件。德国实验室是世界上设备最好的实验室之一，将提供其他地方无法提供的测试能力。研究结果对研制性能更高、寿命更长的液压机械具有重要意义。

9905631ArndtThis award supports Roger Arndt from the University of Minnesota-Twin Cities in a collaboration with Andreas Keller of the Oskar von Miller Institute of the Technical University of Munich located in Obernach, Germany. The project will focus on the study of the formation of periodic cloud cavitation in the trailing edge of hydrofoils. Pumps, hydroturbines, and marine propulsors must often operate in the cavitating regime where pressure is low, causing bubbles to form, which can damage internal machine parts. The German laboratory is one of the best equipped in the world, and will provide test capabilities available nowhere else. The results of the work will be important in the development of higher-performance and longer-lasting hydraulic machinery.
