Abstract
Two-phase critical discharge phenomena have been under investigation for some time now. Most models developed so far have necessitated a knowledge of the critical pressure to predict the critical flow rate. This type of analysis has limited application, as in most cases, only the stagnation conditions are fixed and it is the critical exit pressure that adjusts itself to the stagnation conditions. Thus to be most useful, a model is required to predict both the critical pressure and the critical mass flux from the stagnation conditions only. A model has been developed that is useful in predicting the, adiabatic one-component, two-phase, critical flow of fluids in circular tubes of length to diameter ratios greater than 8. This model which emphasized the flow pattern that is occurring, allows predictions to be made using the stagnation temperature and pressure and L/D only. For a particular stagnation enthalpy the critical mass flux was found to be a function of the conditions at the exit only. The procedure begins by using a trial exit pressure and the actual stagnation enthalpy to find a critical mass flux. Using this critical mass flux, the stagnation pressure is found by integrating upstream from the exit conditions...
