基于涡流发生器的高速液氧泵空化被动控制
Vortex Generator-based Passive Control of Cavitation in a High-speed Liquid Oxygen Pump
摘要
Abstract
This paper aims to investigate the impact of vortex generator application on cavitation with-in a high-speed liquid oxygen pump.Due to the limitations of traditional cavitation control methods in en-hancing the cavitation performance of high-speed liquid oxygen pumps effectively,this paper proposes a cavitation control strategy based on vortex generators for high-speed pump applications.Builded on previ-ous research on water wing cavitation control,numerical simulation methods were employed to analyze the effects of different vortex generator placement methods on the pump's erosion resistance.The research res-ults demonstrate that vortex generators can reduce the dissipative losses caused by turbulent fluctuations,but their influence on cavitation varies depending on their specific positions.By identifying the optimal placement of vortex generators,it was found that positioning them at 120°and 150°from the leading edge achieves better erosion resistance performance.At these positions,the cavitation volume within the im-peller,as well as the vortex intensity,are significantly reduced,which leading to a decrease in the NPSHc.The findings of this study provide valuable insights for cavitation control in high-speed liquid oxygen pumps.关键词
