boundary condition at free surface
hi,
what boundary conditions are to be given at free surface while modelling it in VOF can anyone tell me. i am giving it as wall with shear stress as zero. |
Re: boundary condition at free surface
I too keep the free surface as wall with specified zero stress when modeling fluid flow in tundish. If you do not consider heat transfer then you can change the free surface to be symmetry or pressure inlet condtion. Pressure inlet is what FLuent recommends but I am not sure how because pressure inlet will then ask for velocity and turbulence parameters.

Re: boundary condition at free surface
hi,
actually i am trying to modell free surface flow past cylinder in 2D, i am using VOF, i made 2 zones in gambit only and in fluent now how should i go abt doing it. if u know please suggest. thanks, vineet |
