How interFoam tell which phase is wetting or non-wetting ?
Dear all:
Maybe a stupid question. In interFoam for a given geometry, when we set a case, we give two fluid properties and surface tension in transportProperties, but how interFoam know which fluid is wetting phase and which one is non-wetting phase? When I put surface tension as negative value, time step becomes much shorter and it runs quite slow. Thanks. |
I found it .It is the contact angle that determine which is wetting or non-wetting.
