气液分层流相间摩阻系数计算模型的比较

Comparison to Expression of Hydraulic Frictional Resistance Coefficient Between Stratified Flow of Gas and Liquid Multiphase

介绍了目前常用的6种气液分层流相间摩阻系数计算关系式。根据双流体模型编制了分层流计算程序,采用各种相间摩阻系数计算关系式计算,与在多相流试验装置上得到的数据进行了比较。结果表明,在分层流水力计算中,各种相间摩阻系数的计算关系式对结果影响很大,Andritsos&Hanratty关系式计算结果与试验数据吻合最好。

This paper introduces the calculation equations of hydraulic frictional resistance coefficient of 6 kinds of gas liquid phases given by present literatures,develops the stratified calculation program on the basis of bio-liquid model and compares the calculation results of hydraulic friction resistance coefficient to experimental data obtained from the multiphase liquid device. Different equations of hydraulic frictional resistance coefficient lead to different results and equation of Andritsos & Hanritty give the result that approaches experiment data.
