SUBOFF潜艇回收AUV流场的数值计算

摘要

由于水下远距离传递信息困难,以及受自身携带能源的限制,水下无人航行器(AUV)需要通过母船回收进行能源补充与信息传递.为研究AUV水下回收时的复杂流场,本文基于STAR-CCM+软件,采用重叠网格技术对于潜艇回收AUV时的流场进行研究,分析了AUV在回收过程中受到的压力、流场中的漩涡和速度分布等水动力性能,为水下回收AUV提供了有益的参考.%In order to analyze the complex flow field of the underwater recovery of AUV via submarine , this passage adopts overset meshes to calculate. The overset mesh includes two separated part, which is background region and overset region. When AUV is moving ,the overset region follows. Pressure velocity and other related cloud picture in two different situation provides an effective reference for the underwater docking.
