Hello
I知 simulating a mine tunnel where the walls are very rough (0.55 m rough in a 6 m Dia. tunnel). In CFX I just set up wall roughness under the K-epsilon model in the wall boundary condition. However I want to run a comparison in Openfoam but I don稚 know how to setup such a roughness? I知 using simpleFoam for this simulation. Any help? Thanks, Nestor |

Hi Nestor,
I think this link can help you: http://openfoamwiki.net/index.php/Ho...eWallRoughness In this case the roughness would be constant for every wall. If you wanted to have a different roughness for each wall I think you should add the roughness as a boundary condition. I hope it is helpful, Xabi Quote:

Hi Xabi
Thanks for your answer. I have another question: how can I set up the wall roughness as a boundary condition? Regards. Nestor Last edited by ruedavallejo; April 17, 2009 at 00:27. Reason: Adition of comment |
