Contact angle between different phase and wall
I am trying to simulating a droplet made of oil drop into a water base.
However, I am confusing about setting up the Contact Angle between phase and between phase and wall.
Can anyone give me some suggestions please?
The second water-air is on a different patch (lowerWall as opposed to sideWall) because you can set the contact angle on each patch individually to be able to model a real-life situation in which maybe one wall is wetting with respect to the water and another wall is non-wetting (think of a glass lid and a teflon wall in a cooking pan for example).
Setting up the contact angles with the walls is just a matter of changing the 90s into something else. So to give an example: if you set the following:
I am not that familiar with the multiPhaseInterFoam so I don't know what the 3 zeros in the boundaryField settings mean, but they seem like dummy variables to me. To confirm that you would have to dig into the solver code a bit.
