Computational Simulation of Stationary and Nonstationary Discharge of Adiabatically Boiling Liquids from Short Tubes

RÉSUMÉ

On the basis of a previously developed model of the dynamics of a vapor bubble ensemble a qualitatively new approach to modeling is proposed to analyze both stationary and nonstationary flashing flows in short channels and ducts. The distinguishing feature of the model is the consideration of pressure and temperature differences between the vapor and liquid phases of the flow with due account of thermodynamic nonequilibrium. The model in view is capable of determining the basic parameters of two-phase flows in an arbitrary cross section of the channel at any instant. This approach to modeling is shown to be useful in predicting the transition to the critical flow regime and clarifying the mechanism of a loss-of-flow accident. Calculated data on discharge of saturated water through a tube over a wide range of temperatures in comparison with corresponding experimental results are presented.
