摘要: 在全面调研了国内外关于偏心环状管道层流的研究文献之后,发现几乎都利用经验公式或近似估计式进行水力计算,这与石油工业中的广泛应用不相适应。根据流体力学中N-S方程对层流的描述,再结合力学理论,对偏心环状管流的界面提出严密而科学的界面耦合条件,得到了完整描述偏心环状管流的适定的偏微分方程组,然后通过数值模拟,得到了偏心环状管流的数值解。

Abstract: In the paper, after reading literatures on eccentric annular flowing in the pipe, the hydraulic computation almost was empirical formula or evaluated approximately. According to N-S equations of hydromechanics and mechanics, the interface coupling equations on eccentric annular flowing in the pipe were
scientifically and strictly put forward, and a system of partial differential equations was obtained. By numerical computation,the important flowing laws on eccentric annular flowing were got.

Key words: oil and gas gathering, two-phase flow, eccentric flow, numerical simulation
