Under negative pressure and high-speed conditions, the variation gradient of cavitation characteristics with various inlet negative pressures is non-linear and has a sudden change, but the trend becomes stable after the inlet negative pressure drops to a certain stage. The tip clearance cavitation characteristics vary from the blade surface cavitation characteristics due to the difference in forces on both sides. This study is a proper starting point for the design of aerospace power pumps.<\/jats:p>","DOI":"10.1038\/s41598-024-57822-4","type":"journal-article","created":{"date-parts":[[2024,3,29]],"date-time":"2024-03-29T16:01:44Z","timestamp":1711728104000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The cavitation characteristics of aerospace high-speed centrifugal pumps with different tip clearance"],"prefix":"10.1038","volume":"14","author":[{"given":"Wen-xiong","family":"Chao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wang-cheng","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gao-yang","family":"Bai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Dong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,3,29]]},"reference":[{"key":"57822_CR1","volume-title":"Modern Pumps Technical Manuals","author":"X Guan","year":"2014","unstructured":"Guan, X.
