Abstract

Abstract

In one-dimensional two-fluid model, the interfacial resistance is a key parameter for determining the degree of coupling between phases. At present, the calculation methods include drift-flux model method and resistance coefficient method. In this study, by using the subchannel program, the two calculation methods are evaluated based on the circular tube air-water two-phase experimental data. The results show that the prediction ability of the drift-flux model method in the one-dimensional two-fluid model is better than that of the resistance coefficient method. At the same time, the influence of distribution effect on the calculation of interfacial resistance in two-phase flow is evaluated. The results show that the effect is small in the low void fraction region, but obvious in the high void fraction region.
