Development and validation of a boiling model for OpenFOAM multiphase solver

    Research output: Contribution to conferenceConference articleScientific


    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
