Abstract

This work presents an investigation of the current capability of the interfacial area transport equation (IATE) in subcooled boiling flow. A review of past IATE development efforts in phase-change flow is provided, focusing on the source and sink modeling. By incorporating recent modeling efforts of the condensation sink term and evaporation source term, the framework for prediction of IATE in subcooled boiling is updated and benchmarked against experimental data. This one-dimensional interfacial area transport equation benchmark which implements recently proposed source and sink models extends the range of benchmarked conditions through comparison against recently available experimental data. The results show that the IATE model is capable of accurate prediction of subcooled boiling.
