Class
|
||||
Foam::fv::VoFSolidificationMeltingSource
|
||||
|
||||
Description
|
||||
Solidification and melting model for VoF simulations.
|
||||
|
||||
The presence of the solid phase in the flow field is incorporated into the
|
||||
model as a momentum porosity contribution; the energy associated with the
|
||||
phase change is added as an enthalpy contribution. The solid fraction as a
|
||||
function of temperature \c alphaSolidT is specified as a Foam::Function1.
|
||||
|
||||
The model writes the field \c alpha[01].solid which can be visualised to to
|
||||
show the solid distribution.
|
||||
|
||||
Usage
|
||||
Example usage:
|
||||
\verbatim
|
||||
VoFSolidificationMeltingSource1
|
||||
{
|
||||
type VoFSolidificationMeltingSource;
|
||||
active yes;
|
||||
|
||||
selectionMode cellZone;
|
||||
cellZone solidZone;
|
||||
|
||||
alphaSolidT table
|
||||
(
|
||||
(330 1)
|
||||
(335 0)
|
||||
);
|
||||
|
||||
L 334000;
|
||||
}
|
||||
\endverbatim
|
||||
|
||||
Where:
|
||||
\table
|
||||
Property | Description | Required | Default value
|
||||
alphaSolidT | Solid fraction as function of temperature | yes |
|
||||
L | Latent heat of fusion [J/kg] | yes |
|
||||
relax | Relaxation coefficient [0-1] | no | 0.9
|
||||
Cu | Model coefficient | no | 100000
|
