deldar In the log layer the velocity profile can be estimated with the log law:

$u^+ = \frac{1}{\kappa} \, ln(y^+) + C$

Where:

$u^+$	Dimensionless velocity
$y^+$	Dimensionless wall distance
$\kappa$	von Karman's constant ( $\approx 0.41$ )
$C$	Constant ( $\approx 5.1$ )

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?
