摘要：

Assessments on the combinations of the population balance model (PBM) and wall boiling model are meaningful for the calculation of the steam generator (SG) of the nuclear power plant (NPP). Firstly, the non-dimensional analysis between the report experiment and the SG of the NPP are carried out. Then, the influences of the models of the active nucleation site density N(n )combined with the PBM kernels are analyzed. Lastly, the error analysis on the combinations is illustrated. The results show that the one model combination performs relatively better for the calculation of the Sauter mean diameter (SMD) d(p) (maximum relative error 6.09%), void fraction alpha (maximum relative error 20.06%) and superficial liquid velocity j(l) (maximum relative error 2.06%) of the SG of the NPP. This study demonstrates an integral method and process for the selection of the model combinations in the subcooled boiling flow conditions. (C) 2022 Elsevier Ltd. All rights reserved.
