It's my first post on this forum, hello foamers

I’m trying to simulate slug flow in a capillary tube by using interFoam. I would like to use temperature dependent interfacial tension and contact angle.
I have changed “interfaceProperties” and “twoPhaseProperties” for that. The temperature dependence of the surface tension was made, but the contact angle was not made.

So, I’m using "temperatureDependentAlphaContactAngle" in OpenFOAMv-1706.
I could calculate by setting 0/alpha.water as follows,

wall
{
    type             temperatureDependentAlphaContactAngle;
    theta0          constant 60;
    limit             gradient;
    value            uniform 0;
}

but it has not been changed depending on the temperature. Even if I look at usage, I don’t know how to give temperature dependency. How do I set it

Could anybody please help me.
Thanks.

have you solved your problem???

Hi, saddy.
Thank you for your reply.

Yes, I have been solved problem.
However, I changed "twoPhaseProperties", instead of use "temperatureDependentAlphaContactAngle" to solve problem.

which openfoam version did you compile it for?//

[nitk]

I compiled library in OpenFOAM-2.3.1.
not OpenFOAM-v1706.
