Replacing the specific twoPhaseChangeModel with a consistent and general fvModel
interface will support not just cavitation using the new compressible
VoFCavitation fvModel but also other phase-change and interface manipulation
models in the future and is easier to use for case-specific and other user
customisation.
Class
Foam::fv::compressible::VoFCavitation
Description
Cavitation fvModel
Usage
Example usage:
\verbatim
VoFCavitation
{
type VoFCavitation;
libs ("libcompressibleVoFCavitation.so");
model SchnerrSauer;
KunzCoeffs
{
pSat 2300; // Saturation pressure
UInf 20.0;
tInf 0.005; // L = 0.1 m
Cc 1000;
Cv 1000;
}
MerkleCoeffs
{
pSat 2300; // Saturation pressure
UInf 20.0;
tInf 0.005; // L = 0.1 m
Cc 80;
Cv 1e-03;
}
SchnerrSauerCoeffs
{
pSat 2300; // Saturation pressure
n 1.6e+13;
dNuc 2.0e-06;
Cc 1;
Cv 1;
}
}
\endverbatim
The cavitating ballValve tutorial has been updated to use the new VoFCavitation
fvModel.
