Detailed Description

Contact-angle boundary condition for multi-phase interface-capturing simulations. Sets of coefficients are given for the contact angle with each other phase. These coefficients can specify either a constant or a dynamic contact angle.

Usage

Property	Description	Required	Default value
`theta0`	Equilibrium contact angle	yes
`uTheta`	Velocity scale	no	none
`thetaA`	Limiting advancing contact angle	if uTheta	none
`thetaR`	Limiting receding contact angle	if uTheta	none

Example of the boundary condition specification:

    <patchName>
    {
        type            alphaContactAngle;

        contactAngleProperties
        {
            // Constant contact angle with air
            air
            {
                theta0          90;
            }

            // Dynamic contact angle with water
            oil
            {
                theta0          70;
                uTheta          1;
                thetaA          100;
                thetaR          50;
            }
        }

        value           uniform 0;
    }
