The free surface and pycnocline wake characteristics of SUBOFF were studied by simulations and experiments in a two-layer ocean. The experimental results showed that the simulation method accurately calculated the wake characteristics of the scaling model, and the simulation method was expanded to full-scale prototypes. When typical Froude numbers of flow is from 0.05 to 2.7, the submerged body velocity can influence the wake characteristics of the free surface and pycnocline interface. The wake system of the free surface would transform into a Kelvin wake, and the angles of the V-shaped divergent waves of the pycnocline interface would be reduced with the increasing Froude number.

通过两层海洋中的模拟和实验研究了SUBOFF的自由表面和密斜尾流特征。实验结果表明，该仿真方法准确计算了缩比模型的尾流特性，并将仿真方法扩展到全尺寸原型机。当典型的弗劳德数为0.05至2.7时，水下体速度会影响自由表面和密斜界面的尾流特性。自由表面的尾流系统将转变为开尔文尾流，并且密斜界面的V形发散波的角度将随着弗劳德数的增加而减小。
