摘要
本文对斯仑贝谢的滑脱速度方程和顿斯—罗斯的滑脱速度方程在理论上进行了分析并用实验数据进行了验证,指出了其不足之处和使用的范围。根据大量的实验数据分析,本文提出一种新的滑脱速度方程。
Having analysed in theory and Verified with experimental data about Schlumberger' s and Ros-Duns' slip velocity equations, some shortcomings and limitations have been pointed out in this paper. The paper gives a new slip velocity equation which is used to calculate each phase fluid apparent velocity of mixed gas-liquid flow in vertical pipes, and the calculated results from the new equation are very close to the experimental data. The relative errors are below 5%.
