摘要
为掌握大攻角条件下轴对称航行体的空泡形态以及表面压力分布特征,本文对不同攻角,不同空泡数条件下轴对称航行体的流体动力特性进行了水洞试验研究,获取了不同试验条件下空泡的不同形态和压力分布。试验结果分析表明,在大攻角状态下,航行体表面的空泡分布不对称性加剧,迎背水面压差作用范围加大,导致航行体法向受力加大。研究结果在工程设计中有重要意义。
An experiment was carried out for investigating the cavitation patterns and pressure distribution on an underwater vehicle’s surface with different angles of attack and cavitation number. The pressure distribution was measured on the side facing to the inflow as well as on the backside. Each side setup 21 measuring points. The cavitation behavior was observed. This paper presents some of the pressure measurements results and cavitation photos. The test is also described.
