摘要
对美国DARPA潜艇模型SUBOFF尾流场进行了数值模拟,采用湍流模型k-ε、k-ω与壁面函数相结合,直接求解RANS方程,并将计算结果与试验结果进行了比较分析,验证了数值方法的可靠性。在此基础上将SUBOFF模型改变为“X”型尾翼,对其尾流场进行了数值模拟分析。
The wake field of a hypothetical submarine model DARPA SUBOFF is simulated numerically by solving RANS equations with κ-ε、κ-ω turbulence models and wall functions. By comparing the computational results with the experimental data, the numerical results prove creditable. Moreover the wake fields of fins in the shape of ＂X＂ are also simulated and analyzed.
