WebAs a second example, consider the profiles of mean and turbulent velocity measured across a jet. The profiles are self-similar when normalized by the centerline velocity, UCL. The maximum turbulence level occurs at the positions of maximum shear. At the centerline the shear is zero (∂∂=uy0), and the turbulence strength is diminished.
