Extract

It has long been suspected that the inner portion of any turbulent boundary layer velocity profile obeys a so-called law of the wall which takes the form:

where u is the boundary layer velocity at a distance y from the wall, uτ is the friction velocity given by √(τw/ρ) in which τw is the wall shearing stress and ρ is the fluid density, v is the kinematic viscosity and A and B are constants.
