Rough walls in low Re -- CFD Online Discussion Forums

August 2, 2018, 03:55	Rough walls in low Re	#1
kandelabr Senior Member Nejc Join Date: Feb 2017 Location: Slovenia Posts: 196 Rep Power: 9	I have a case of a flow in a thin gap with rough walls. I know about nut*RoughWallFunctions but these require cells greater than the gap itself. For low-re cases, there are no wall functions, hence no rough walls can be selected. How do I model rough walls in low Re cases? Thanks!
