Model Prediction and Measurement for Multiphase Flow Phase Holdup

在多相流工艺计算中 ,相分率是多相流中一个非常重要的参数。准确预测和测量相分率 ,对于多相混输管道的流量测量、工艺计算和优化运行具有重要意义。

During the exploitation process of the oil and gas fields, the fact that the transportation of oil-gas water three-phase flow has distinctive economic advantages has stimulated the researches on multiphase transportation technologies. In the multiphase flow calculation, phase holdup is an important parameter. Predicating and measuring phase holdup correctly play important role in flux measurement, technical calculation and optimum run of multiphase flow pipelines. Therefore, concerned scholars have brought forward many models to calculate holdup and correlative measurements and equipments. This article introduces the models predication and measurement methods on the phase holdup presented by concerned scholars.
