采用计算流体力学中 VOF模型对水平突扩管和突缩管内油水两相流进行数值模拟，两相流中原油为中质稠油并且含水率较高，从50%到80%不等。结果表明，不同含水率油水两相流在突扩管和突缩管内主要为水包油流型，在管径突变处压力波动变化明显，但含水率从50%变化到80%时对压力变化趋势影响较小。得到的不同含水率油水两相流在突变管径管道中的流动规律，可为原油集输管网油水两相流混输问题提供参考。

Using the VOF model of computational fluid dynamics to simulate oil-water two-phase flow in horizontal sudden expansion pipe and contractible pipe,the crude oil in the two-phase flow is medium viscous oil and the moisture content is high, ranging from 50% to 80%.The results show that:the different water content flow in oil-water two-phase flow in the sudden expansion pipe and sudden contraction pipe belong to oil-in-water stream,the pressure fluctuation in diameter mutation changes obviously,but the pressure change trend is affected little when the moisture content changes from 50% to 80%.Flow in the mutant diameter pipes with different water content of oil-water two-phase flow pattern obtained can provide certain reference when involving mixed oil-water two-phase flow transportation problems in crude oil pipeline.
