Trouble with Simple Flow Through Pipe

tl12345 · July 18, 2018, 00:52

Hi, I'm trying to simulate 3D flow of water into a 1.6mm diameter tube filled with air. I'm using VOF with PISO, surface tension enabled and set to 0.073N/m, a water inlet velocity of 0.005m/s, a pressure outlet with gauge pressure of 0, wall adhesion enabled and set to 75 degrees, a time step of 0.001s, and the standard laminar flow model.

I've looked at many tutorials and forums and played with just about every parameter I can think of, but cannot get reasonable results. Does anyone have any suggestions?

Hi,

Can you elaborate on what difficulties you are facing. What results are unreasonable.
