1·In ocean engineering realm, fluid drags are computed by Morison equation with drag coefficient defined by a function of Renold number and attack Angle.

在海洋工程领域，计算软管流体阻力采用莫里逊公式，其中阻力系数是双参数迎角和雷诺数的函数。

2·After concentrated introduction of the conception of DVM, a simplified numerical model is proposed under high Renold number which is a DVM model combined singularity method.

在集中介绍离散涡方法的概念后，提出在高雷诺数流动情况下的一种简化流动模型—基于奇点法的离散涡模型。

3·The N-S and Possion equations were calculated by using the velocity and pressure modification method at the same time. The surrounding current field at lower Renold number was then obtained.

同时采用速度压力修正法求解n - S方程和泊松压力方程，得到了雷诺数较低条件下的水平输油管线周围的流场分布。
