duaiduaihu is on a distinguished road
in fluent,when we activate wall adhesion in phase interanction ,we can define the contact angle .
my question is the contact angel should be the angel between phases,can we define the contact angle(wetting angel )between phase and wall?

i am working on the oil carrying the residual water in inclined the experiment,the water is distributed alone the inclined pipe(upward) at certain velocity of the oil.but the CFD result is that the water could be taken away only the time is long i think it might be related with different wetting angles of the phases(oil and watet) with wall.

can you give me some ideas!
