RT Journal Article ID 3bdccc5f2101145e A1 VADLAMUDI, SAI RAJA GOPAL A1 Nayak, Arun Kumar T1 EFFECT OF BOILING AND MOMENTUM CLOSURES ON THE PREDICTION OF SUBCOOLED FLOW BOILING JF Multiphase Science and Technology JO MST YR 2019 FD 2020-01-07 VO 31 IS 4 SP 319 OP 344 K1 subcooled boiling K1 CFD flow boiling K1 momentum closures AB Flow boiling is widely used as a mode of heat transfer in many industries, especially in nuclear reactors. Despite its advantages, heat transfer is hampered beyond certain flux under subcooled boiling conditions due to a phenomenon known as departure from nucleate boiling. It is important to determine the void fraction profiles, especially the near-wall void fractions, in order to evaluate the limiting heat flux conditions. Many researchers used the two-fluid Eulerian model coupled with the wall boiling model to predict the subcooled flow boiling in vertical tubes. However, there is no common consensus regarding the boiling and momentum closures. In this paper, a comprehensive analysis is performed to analyze the impact of boiling and momentum closures. Simulation results are validated with experimental data of DEBORA tests. PB Begell House LK https://www.dl.begellhouse.com/journals/5af8c23d50e0a883,66a03c6711c437b6,3bdccc5f2101145e.html
