Simulation of subcooled boiling in multiphase CFD code CFX

Popis výsledku v původním jazyce

This paper presents a validation of multiphase computational fluid dynamics (CFD) code Ansys CFX 18 on selected experiments 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 phenomena in boiling bubbly flow was selected and tested on the following experiments with subcooled boiling: DEBORA experiments, 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 experiments. 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.
