动态双流体模型在两相流系统的模拟中得到了广泛的应用，特别是在核反应堆堆芯的蒸汽/水流动分析中。然而，直到最近，很少有人尝试使用这种模型来模拟管道中的油气两相流。本文详细介绍了一种动态双流体模型OLGA，着重介绍了基本方程和所采用的双流体模型。稳态压降，持液量和流型转变的预测进行比较，从SINTEF两相流实验室和文献中的数据。与评价的现场数据的比较。
Dynamic two-fluid models have found a wide range of application in the simulation of two-phase-flow systems, particularly for the analysis of steam/water flow in the core of a nuclear reactor. Until quite recently, however, very few attempts have been made to use such models in the simulation of two-phase oil and gas flow in pipelines. This paper presents a dynamic two-fluid model, OLGA, in detail, stressing the basic equations and the two-fluid models applied. Predictions of steady-state pressure drop, liquid hold-up, and flow-regime transitions are compared with data from the SINTEF Two-Phase Flow Laboratory and from the literature. Comparisons with evaluated field data are also presented.
