Abstract
To measure two-phase flow mass flowrate and stream quality is an essential issue in the study of LOCA (loss-of-coolant accident). The authors have derived a model, which uses statistic average value of differential pressure square root and statistic variance of a throttling set in a two-phase flow system, to estimate the mass flowrate and steam quality. The correctness of the model has been proved in the orifice experiment of a two-phase flow system at pressure range of 5.8{approx}12.1 MPa and steam quality from 0.05{approx}0.95, and a practical, semi-theoretical and semi-empirical model is fitted. The rms errors of mass flowrate and steam quality estimated by this model are 9.0% and 6.5% respectively. The result from this study creates a method to measure two parameters in a two-phase flow system using a single orifice.
