摘要 本研究使用基于RANS方程和VOF方法的非定常粘性数值方法对潜艇在两层流体中水下运动时的尾迹特征进行了探索性研究,成功的模拟出潜艇水下运动产生的表面波和内波,数值计算结果与理论分析和文献研究结果基本一致。 An unsteady viscous numerical method based on RANS equations and VOF method was used to simulate the wake characteristic of a submarine moving in a two-layer fluid, the surface wave and internal wave generated by the submarine was obtained successfully, numerical results were in good agreement with theoretical analysis and results from literatures.
