摘要
针对气液混输管线与悬链线立管系统严重段塞流问题,采用严重段塞流形成条件一致的等效原则,发展了一种将三维管道系统等效为二维管道系统的计算流体力学(CFD)数值模拟方法。以文献中某水平/下倾管与悬链线立管组合系统为对象,结合其实验工况,数值模拟了该种管型下的严重段塞流现象,分析了其压力波动幅值及周期变化特性,数值模拟与文献所述实验结果一致,表明了该数值模拟方法的有效性。
Based on the consistence principle for the severe slugging formation condition, a CFD （Computational Fluid Dynamics） method was proposed for numerically simulating the gas-liquid severe slugging in a pipeline-riser system by means of translating the 3D pipeline- riser system into a 2D equivalent one. Numerical simulations were conducted for the gas-liquid flow patterns of the severe slugging in a horizontal/declination pipeline-catenary riser system according to the experimental cases presented in the reference, and the pressure characteristics including period and its amplitude were analyzed due to such a severe slug flow, the numerical results are good agreements with the experimental ones in the refrence showing that the proposed method is effective.
