Abstract

A model is developed that is useful in predicting from stagnation conditions alone the adiabatic, one component, two-phase, critical mass flow rate of fluids in circular tubes of length to diameter ratio greater than 8. This model emphasizes the flow regimes that are present and the phenomenological correctness of the model is demonstrated by using two other tests as well: first the prediction of critical mass flow rate for a given critical pressure and stagnation enthalph and secondly, the prediction of the pressure profile in the long tube. Charts of the critical mass flow rate versus stagnation pressure with stagnation temperature as the second independent variable are obtained using the model. (from authors' abstract)
