Description🔗
The fluxCorrectedVelocity is a velocity-outlet boundary condition that
corrects the extrapolated velocity to match the specified flow rate.
Usage🔗
The condition requires entries in both the boundary and field files.
Boundary file🔗
<patchName>
{
type patch;
...
}
Field file🔗
<patchName>
{
// Mandatory entries
type fluxCorrectedVelocity;
// Optional entries
phi <word>;
rho <word>;
// Inherited entries
...
}
where:
| Property | Description | Type | Required | Default |
|---|---|---|---|---|
type |
Type name: fluxCorrectedVelocity
|
word | yes | - |
phi |
Name of flux field | word | no | phi |
rho |
Name of density field | word | no | rho |
The inherited entries are elaborated in:
- fvPatchFields.H
- zeroGradientFvPatchFields.H
Method🔗
\[\mathbf{u}_p = \mathbf{u}_c - \mathbf{n} (\mathbf{n} \cdot \mathbf{u}_c) + \frac{\mathbf{n} \phi_p}{|\mathbf{S}_f|}\]where:
| Property | Description |
|---|---|
| \(\mathbf{u}_p\) | Patch velocity [m/s] |
| \(\mathbf{u}_c\) | Velocity in cells adjacent to the patch [m/s] |
| \(\mathbf{u}_c\) | Patch-normal vectors [-] |
| \(\phi_p\) | Patch flux [m^3/s] or [kg/s] |
| \(\mathbf{S}_f\) | Patch face area vectors [m^2] |
