摘要
潜艇水池试验与深广水域航行区别很大,采用计算流体力学(CFD)方法研究试验连接装置及试验水池尺度对潜艇试验的影响。首先对深广水域的潜艇进行计算,以此来校核CFD算法;然后对潜艇试验实况进行建模计算,根据计算结果来分析模型连接件、池壁和池底效应等对于潜艇受力测试的影响;最后结合实际试验和仿真计算结果,分析并证明试验装置的可行性。
The submarine model test in a towing tank is greatly different from the test conducted under the unlimited condition. This paper studies the influences of the connection device in test and the size of the towing tank size on the submarine model test by the computational fluid dynamic（CFD） method. The submarine sailing in the unlimited condition is firstly simulated to check and evaluate the CFD settings. Then, the submarine model test in towing tank is modeled and calculated. The results are analyzed to investigate the effects of the connection devices, the side wall and the bottom on the force measurement. Finally, the numerical simulation results are combined with the model test results to verify the feasibility of the test facilities.
