Re: SST K-Omega boundary conditions and mesh properties

Hi Dmitry, Regarding your first question, I think Boundary Layer Thickness is not the Y+ (non-dimensional) thickness, but the actual physical thickness. At the end of the second chapter of the ModelsManual it says - this is the distance from the boundary node of the meshed domain to the physical wal...

Re: Navier-Stokes with K-Epsilon Solver - Mass not Conserved

Hi All, Here is the new result - and the mass balance looks much better now. What I did was : (1) made the mesh overall finer, very fine on the inlet and outlet nozzles and (2) no slip bc (without wall law) on the nozzle patches and wall law on the interior walls as before. Please see new picture at...

Re: Navier-Stokes with K-Epsilon Solver - Mass not Conserved

@dmitry, @annier: Thanks for the inputs - Velocity 1 = 0 is not the problem as Anil Kunwar points out because I've turned on the "Normal-Tangential velocity = True" flag, which ensures that the flow doesn't pass through the wall. @raback: Thank You Peter for your comments. Using higher ord...

Navier-Stokes with K-Epsilon Solver - Mass not Conserved

Dear Elmer Group, I use OpenFOAM quite a bit for fluid flow calculations and am now starting to use Elmer for its impressive array of multiphysics capabilities. Thank you Elmer Developers for this wonderful software suite. I am trying to model the recirculatory flow induced by a jet in a simple 2D t...
