输油管线升力的数值模拟与实验研究

Numerical Model Simulation and Experimental Research on the Lifting Force of Marine Oil Pipeline

在波浪场中 ,利用 PIV装置进行水平输油管线升力及其周围流场的同步测量。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。

The synchronistical measurement for marine pipeline lifting force and surrounding current field in wave field was carried out by introducing a PIV system method.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.The two results were compared,analyzed and discussed.
