Incompressible zero-pressure-gradient turbulent boundary layer: An assessment of the data

The available data describing the incompressible zero-pressure-gradient boundary layer are reviewed in association with a range of studies which are either new or, to date, not very generally available. The new data cover a Reynolds number range 2.5 < Re-delta 2 x 10(-3) < 58 and include measurements of all three turbulence perturbations and the Reynolds shear stress. They are assessed in relation to data in the range 0.4 < Re-delta 2 x 10(-3) < 211 using established scaling laws. In common with other investigators we find that while scaling the mean Row leads ro a high degree of apparent similarity, scaling of the turbulence quantities is in general not so satisfactory.
