Abstract: 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.

摘要: 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5 0%到8 0%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5 0%变化到8 0%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。
