General alpha contact angle boundary condition.
The essential entry "limit" controls the gradient of alpha1 on the wall:
Note that if any of the first three options are used the boundary condition on p_rgh
must set to guarantee that the flux is corrected to be zero at the wall.
Property | Description | Required | Default value |
---|---|---|---|
limit | Limiting option | yes | |
contantAngle | Contact angle model settings | no | none |
Example of the boundary condition specification for a constant angle:
<patchName> { type contactAngle; limit none; contactAngle { type constant; theta0 70; } }
If the contactAngle sub-dictionary is not given, a constant angle will be assumed. Example:
<patchName> { type contactAngle; limit none; theta0 70; }
