Description
A dynamic alphaContactAngle scalar boundary condition
Usage
Standard properties:
\table
Property | Description | Required | Default value
theta0 | Equilibrium contact angle | yes |
uTheta | Velocity scale | yes |
\endtable
The advancing and receding contact angles can be either specified with
respect to the interface normal direction:
\table
Property | Description | Required | Default value
thetaA | Limiting advancing contact angle | yes |
thetaR | Limiting receding contact angle | yes |
\endtable
or with respect to the phase outward direction:
\table
Property | Description | Required | Default value
thetaAdv | Limiting advancing contact angle | yes |
thetaRec | Limiting receding contact angle | yes |
\endtable
Example of the boundary condition specification using the interface
normal direction convention:
\verbatim
<patchName>
{
type dynamicAlphaContactAngle;
uTheta 1;
theta0 90;
thetaA 70;
thetaR 110;
limit gradient;
value uniform 0;
}
\endverbatim
Example of the boundary condition specification using the phase outward
direction convention (opposite to the normal direction):
\verbatim
<patchName>
{
type dynamicAlphaContactAngle;
uTheta 1;
theta0 90;
thetaAdv 110;
thetaRec 70;
limit gradient;
value uniform 0;
}
\endverbatim
