April 7, 2009, 01:39	Wall roughness	#1
ruedavallejo New Member Nestor Rueda Join Date: Mar 2009 Posts: 9 Rep Power: 17	Hello I’m 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’t know how to setup such a roughness? I’m using simpleFoam for this simulation. Any help? Thanks, Nestor
