Law of the wall
From CFD-Wiki
In the log layer the velocity profile can be estimated with the log law:
and close to the wall in the viscous sublayer
Where:
Dimensionless velocity Dimensionless wall distance von Karman's constant () Constant ()
We should have a lin-log plot here of a typical turbulent boundary layer to illustrate where the log-law is valid, anyone have one handy?
