Simulation of subcooled boiling in multiphase CFD code CFX
Original language description
This paper presents a validation of multiphase computational fluid dynamics (CFD) code Ansys CFX 18 on selected experi- ments with the subcooled boiling flow. Ansys CFX code can simulate multiphase flow by solving three balance equations for each phase (Euler-Euler approach). Boiling on the heated wall can be simulated with the model proposed by Kurul and Podowski. A set of mathematical models of physical phenom- ena in boiling bubbly flow was selected and tested on the fol- lowing experiments with subcooled boiling: DEBORA expe- riments, ASU experiments, FRIGG FT-6a experiment, and Bartolomej et al. experiment. It was found out that CFX code can reasonably reproduce measured data in all these experi- ments. At the end of this paper, we present an application of this modeling approach to the real case with a complicated geometry: simulation of subcooled boiling in the VVER-1000 fuel assembly with bent rods.
