Wall roughness and Elog
 
This question has been possed a couple of times with no satisfactory answer. Does anyone know how to relate actual wall roughness(k)or sand grain roughness to the Elog value used in the k-epsilon model of some codes? i am using a code called Flo++ and need to incorporate wall roughness effects. Thanks in advance
