compressibleInterGenericPhaseChangeFoam is a solver for OpenFOAM version 2.3 for simulating compressible cryogenic fluids with generic phase change consisting of inertially-driven and thermally-driven phase change.

Solver features:

• Based on the OpenFOAM® solver: compressibleInterFoam
• Two-fluid mixture flow modeling with separate EOS for each phase
• Volume of fluid (VOF) phase-fraction based interface capturing approach
• Thermally-driven phase change models of Lee and Scharge-Tanasawa
• Inertially-driven phase change models of Kunz and Merkle
• Phase change modeling in terms of user defined vaporization and condensation coefficients (Rv and Rc)
• Energy equation solved in terms of static enthalpy
• Saturation temperature (Tsat) dependence on p (based on Clausius–Clapeyron relation)
• Phase change model coupled with solved temperature and enthalpy fields
• Ability to read generic thermophysical model libraries (e.g. NG, N2, water) for each phase

Installation/compilation instructions:

• In compilation of the solver, there might be some warnings about unused variables in the code; please disregard these warnings as they are related to some other development tasks. The solver should be compiled with no issue, on typical C++ compiler such as Intel g++, gcc, regardless of the warnings.
• In case of compilation error regarding the library called twoPhaseMixtureThermo (this should not happen normally, if you use OpenFoam v2.3.x), use the following

wmake libso twoPhaseMixtureThermo

to compile the library first and then use

wmake

to compile the solver.
