Abstract
On-going development and validation of a boiling model
for the OpenFOAM two-phase solver is described.
The twoPhaseEulerFoam solver of OpenFOAM version 1.7 was
used as a starting point, where enthalpy
equations for two phases were added using phase-intensive
formulation of the transport equations. The same
phase-intensive approach was adopted for the turbulence
model equations. First, closure laws commonly
used in literature for modeling dispersed bubbly air flow
in water were added in the solver, and the solver
was validated. Second, phase change terms were added in
the equations and the RPI model for subcooled
nucleate boiling was implemented and validated.
For modeling dispersed bubbly air flow in water a wide
selection of user-selectable interfacial force models
were implemented. The models were validated by comparing
the results to publicly available DEDALE data.
The RPI model was implemented in the OpenFOAM solver by
using models found in open literature. The
boiling model was validated against publicly available
data from the DEBORA experiment. In addition, the
results were compared to those obtained with commercial
ANSYS FLUENT 14.0.0 code
