Assessment of the TRAC-PF1/MOD1 condensation model
Description
The TRAC-PF1/MOD1 (TRAC) condensation model was assessed against the data of Aoki and Akimoto. Three flow regimes with direct-contact condensation of steam with subcooled water were investigated: annular-mist flow, transition to unstable flow, and oscillating-plug flow. The droplet condensation model proposed by Brown was implemented and tested as well. It was found that the Brown model did not offer a significant improvement over the current condensation model used in TRAC for the case of annular-mist flow. It was found that TRAC was able to predict accurately the transition from stable to unstable flow at the same conditions as observed in the data. For the case of oscillatory-plug flow, TRAC was in moderate agreement with the oscillation frequency and amplitude
