油水两相管流理论的研究进展

Research Progress in the Theory of Oil-water Two-phase Pipe Flow

综述了油水两相流动分层流流型压降理论和分散流流型压降理论的研究进展。对于分层流流型压降理论,着重介绍了研究相对较成熟的双流体模型,其关键在于油水两相界面摩阻因数的计算;对于分散流流型压降理论,介绍了均相流模型,其关键在于油水两相混合液粘度的计算。分析了油水两相管流理论研究存在的问题,提出了针对实际生产需求亟待开展的理论研究方向。

Research progress in pressure drop theory of stratified flow pattern and dispersed flow pattern for oil-water two-phase are reviewed. For the former, two-fluid model, a more mature model in research, is introduced, and the key of which rests with the calculation of frictional drag coefficient between oil-water two-phase interface) for the latter, the key of which rests with thecalculation of oil-water two-phase mixed fluid viscosity. Problems in theory research of the oil-water two-phase pipe flow are analyzed and theory research direction is put forward to meet the urgent needs of actual pipeline operation.
