Hi Foamers,
I'm a new user of OpenFoam, and I've to compare it with Fluent during my training period. I'd like to set up a case of a steady state, incompressible, turbulent flow through an elbow. I wish to use the simpleFoam RAS solver, in order to use the same conditions as in Fluent. Here are my BCs: mass flow inlet at 0.111 kg/s pressure outlet the fluid is air at 200°C: rho=2.065kg/m3, nu=1.24e-05m2/s I've used the pitzDaily case in the simpleFoam tutorial to copy the needed files, and I've changed the name of the patches/walls. I've initialized epsilon and k with suitable values for my case according to the formula given in the User Guide. My calculation converged. The point is the flow seems to be laminar when I look at it in Paraview, although my Re=~123000. There is certainly a mistake in my files but I can't find it. I will appreciate some help. I join my data but the mesh in the attached archive. Thanks a lot for your time. |
