Abstract
Residual Reynolds number effects in the established data for the veloc ity profile in turbulent boundary layers (and in pipe or channel flows ) are found to be remarkably large. We combine two eddy-viscosity mode ls (with overlapping validity in the inertial sublayer) and show (both analytically and numerically) that this enhancement (which involves a viscous correlation length) arises from inner-outer sublayer interact ion.
