Overlap Layer

Overlap layer is in between the wall layer and the outer layer. As the name indicates, both laminar and turbulent shear stresses prevail in this region. The velocity profile is given by the logarithmic law,

$$u^+ = {1 \over \kappa } \ln y^+ + B$$ (7.33)

where the K$\acute{a}$rm$\acute{a}$n constant, $\kappa$ is 0.41and $B\approx 5.0$.
