Hey Foamers,
I simulate a internal pipe gas flow through a high porous structure for different inlet velocities with simpleFoam. I start with Uin = 0.1 and and go to Uin=1.5 m/s. For a velocity of 1m/s I reach convergence. For higher velocities, the solution does not convergence. My question now is: Does this come from a too coarse mesh (already did a grid study for many refinements) or is it because of strating turbulence? Can anybody tell me, how I can identify turbulence in comparison to a mesh problem? Thanks a lot for your info! Best regards |
