摘要
以油气水三相混合物为工质 ,对进口水平、出口垂直向上 90°弯管内油气水三相流的局部阻力特性进行了实验研究 .弯管内径为 4 5mm、弯曲半径为 30 0mm .在实验数据分析和比较的基础上 ,将油气水三相流流过弯管的局部阻力特性在整个实验范围内分为 3个区域 ,提出了各区域内局部阻力损失的计算式 ,计算值和实验值符合良好 .
Experimental investigation is made for the three-phase flow of oil, gas and water entering horizontally into a 90° pipe elbow with a vertical exit. The pipe inner diameter is 45 mm and the bend radius is 300 mm. The observed local pressure characteristics can be divided into three regions, each of which is analyzed. Semi-empirical correlations are made for representing the local pressure drop data.
