摘要
以气水、油气为工质,对水平进口、垂直出口向上的90°弯管内气液两相流局部阻力特性进行了实验研究。通过对内径为45mm、弯曲半径为180mm的弯管试验结果进行分析,总结出了气水、油气两相流体流过弯管时的局部阻力变化规律,重新提出了计算弯管局部阻力的统一计算公式。其计算结果与试验值符合良好。
In this paper,an experimental study of local pressure drop characteristics of gas-water and oil-gas two-phase flow through horizontal inlet,vertical upward outlet 90° bend was conducted. The inner diameter of pipe is 45 mm,the curvature radius of bend is 180 mm. Some comparisons between the experimental data and previous models or formulations were made. Based on experimental results,a new kind of general correlation for predicting local pressure drop of gas-water and oil-gas liquid two-phase flow through bend was proposed. A good agreement was achieved between the experiment and the new kind of general correlation.
