Hello
I am trying to understand if is it reasonable to use "slip walls" or "zero shear stress" to model smooth walls. I am working with turbulent air flows in ducts. Please share your comments. |

Are there materials that would qualify as "slip walls"?
For example, the pipe roughness of glass/drawn brass/copper pipe is 0.0015 mm. Is it wise to enforce "zero shear stress" on such wall? Last edited by jpo; June 18, 2010 at 18:35. |
