Cell Zones
1 Attachment(s)
Hi there,
(3d, pbns, VOF, spe, lam, transient) I'm modeling fluid flows down a narrow pipe (fluids = water and air). In the "cell zone conditions" menu, the only zone I see is air [attachment1]. I believe I should see water and air. Also: I'm trying to add surface tension effects between the walls and the water, but in the menu it appears I can only add the effects between the two fluids. Actually, with the options I've selected, I can't even find the option of setting a wall fluid angle interaction anymore... I have some suspicion that these problems are related. Any ideas? Thanks |
I think it is surface tension between water and air, not water and wall.
go on phase interaction panel and set the water-air surface tension. |
Good point, thanks! I made a slight mistake asking my question: If I want to set a contact angle (say at 90 degrees) with the wall for the water droplet, how do I do that? It doesn't appear I can set it for wall/water, even though in the manual it appears I can do this.
Make sense? |
90 Degree....
just decrease gavity and increase water-air surface tension. |
Ok think I figured it out now! Thanks for your help! In case people are wondering, I was able to set the angle. In a VOF model, I selected "Wall Adhesion" in the momentum tab of the phase interaction. Then I set the angle in the boundary conditions tab.
