Figure 7.11: Velocity and Shear Stress profiles for a Turbulent Boundary Layer

 

Logarithmic Overlap Law

A typical boundary layer velocity profile for a turbulent flow about a flat plate is shown in Fig.7.10. This profile is to be studied along with the shear stress profile also shown in Fig. 7.11. The profile is marked by three distinct zones or layers- (1) Wall Layer, (2) Outer Layer and (3) Overlap Layer.
