Abstract
The fluctuating velocity in the near-wall layer is shown to scale on the fluctuating wall shear stress such that it has the form u '/u 'τ = f (u 'τ y/v) where u 'τ is a velocity based on the r.m.s of the wall shear stress fluctuation and u′ is the r.m.s velocity. The observed dependency on u 'τ y/v which is independent of mean velocity and mean wall shear stress, exhibits a logarithmic region which extends to about 0.1 of the bubble height, and the viscous sublayer is quadratic in behaviour.
