A moving-boundary model of two-phase cryogenic flow, which was developed in the companion paper (HafiychukV.FoygelM.Ponizovskaya-DevineE.SmelyanskiyV.WatsonM.BrownB.GoodrichC., “Moving-Boundary Model of Cryogenic Fuel Loading, I: Two-Phase Flow in a Long Pipe,” Journal of Thermophysics and Heat Transfer, Vol. 29, No. 3, 2015, pp. 524–532.), is applied toward simulation of liquid nitrogen flow data collected for the cooldown regime in two different experimental fuel transfer lines: 1) the 1966 National Bureau of Standards (now the National Institute of Standards and Technology) setup and 2) the novel NASA Kennedy Space Center cryogenic testbed. With relatively small computational effort compared to full-scale schemes, the model describes pressure and temperature histories, kinetics of the vapor void fraction, and interphase boundary motion in two different parts of the transfer lines. The aforementioned time-dependent characteristics are shown to be in a good agreement with the experimental data on the cooldown stage of liquid nitrogen loading obtained at the National Bureau of Standards setup (with no fitting parameters used) and in a fair agreement with the NASA Kennedy Space Center testbed setup (with a small fitting) for chilldown and fast fill operations. The fast and accurate modeling procedure accounts for cryogen fueling operations in both the nominal and major fault regimes.
