摘　　要：采用Realizedk-ε湍流模型求解Reynolds平均Navier-Stokes方程,对SUBOFF全附体模型分别在风洞和水池试验条件下的尾部伴流场进行了三维粘性数值模拟,计算结果同试验结果具有很好的一致性,对两种试验条件进行模拟所得的结果是完全一致的.计算结果表明,在风洞和水池进行水下航行器尾流场试验所获得的结果差异主要是由于测试误差引起的.The calculation of the 3D viscous wake field of a underwater aircraft model SUBOFF with full appendages under wind tunnel conditions and towing tank conditions were made by solving RANS equations with Reahzed K-ε turbulences models. The computed results of wake fieM were comparison with the test data by some reference, and it indicates that the numerical result is consistent with test data, The result of wake fieM in different test conditions were entirety consistent. The result shows that difference of test data on wake field of underwater aircraft should be due to the test error.
