首先应用自由尾流分析技术来计算旋翼尾迹和发动机绕排流空间的洗流速度。
First, free wake analysis was carried out to calculate the rotor wake geometry and the downwash around the engine jet space.
伯努利“水丘”、开尔文尾流、涡尾迹、内波尾迹都起源于潜艇水动力学，对于潜艇的非声探测具有重要的应用意义。
The Bernoulli hump, Kelvin wake, vortex wake and internal wave wake, etc. are generated, as the submarine moves in the ocean. These wake signatures may be used in remote sensing of submarine.
