Modeling Loss-of-Fluid Test Small-Break Experiments with RETRAN

Abstract

Comparisons made between experimental results of loss-of-fluid test small-break experiments L3-1, L3-5, and L3-6 and analyses using preliminary versions of the RETRAN-02 code show that several questions that exist about the experiments confound the code comparisons. It was concluded that the code predicts the broad trends observed in the experiments, however, code improvements may be needed to better model the phase separation and flow stratification effects.
