Free Surface Boundary
I want to model flow around a ship hull. I do not know how to account for the free surface boundary. You may assume that the hull is positioned in an very large body of water.
Thanks in advance. |
Re: Free Surface Boundary
The problem is hard. I tried to do the same at University.
I had good result using simmetry boundary condition on a flat free surface, in a case with low Froude number. I've not obtained good results studying free surface too.I've used Volume Of Fluid method by Hyrth,there are a large literature, see Fluent manuals first. Now I'm trying to use Star-CD, but there are other problems calculating viscous stress and Y+. Good luck Giovanni |
Re: Free Surface Boundary
Hi!
I have had some trouble with the VOF method and other multi-phase in Fluent. I will be shortly trying cfx. I have been told that it is very good on multi-phase. There is a new free-surface model in cfx5, but I haven't tried it yet. I will let you know how I get on! |
Re: Free Surface Boundary
Hi, I think you can try the VOF Model to simulate the flow around a ship's hull. I'm a novice at FLUENT,I want to model flow around a ship's hull also,but i don't know how to import the offset of the ship into GAMBIT for grid generation.Would you please help me. thanks a lot
