摘要

以双流体模型为基础，建立了适用于水平油气混输管路的瞬态数学模型，并讨论了模型的求解以及分层流的结构方程对计算结果的影响。在大型多相流实验环道上进行了大量的混输瞬变流动过程实验，利用实验和现场数据对瞬态模型模拟得到的混输管道中的平均持液率、压降以及瞬变过程的入口压力、持液率等流动参数等进行了验证和计算，结果表明建立的模型可以比较准确地预测油气混输管路中的流动参数。

Abstract

Based on the two-fluid model

a transient model for the simulation of transient process in multiphase pipelines with low loads of liquids was developed. The solution of the transient model as well as the model for the stratified flow was discussed deeply. Moreover

many experiments including pigging and flow rate changing were conducted on the large multiphase flow loop. The model gave very good simulation and accurate forecasts for all kinds of important parameters

which was very satisfying

when it was used to simulate experimental system and the actual multiphase pipeline.
