AbstractThis paper is concerned with the flat plate turbulent boundary layer without pressure gradient. It is shown that the recent measurements almost perfectly follow the Rotta skin friction law derived by assuming the existence of the logarithmic overlap region, and that the Schoenherr empirical formula holds as a high Reynolds number asymptotic form of the Rotta law. We next clarify the Reynolds number dependent mean flow dynamics of the inner wall layer. With these results we discuss usefulness of the so-called combined velocity profile.
