Abstract
The Reynolds number dependence is estimated for the wall-normal position at which the turbulent and viscous shear stresses are equal. For large Reynol ds numbers, this position coincides with the peak location of the mean mome ntum transport terms due to turbulent and viscous action. Experimental data are used to corroborate the results and assess some quantitative details. (C) 1999 American Institute of Physics. [S1070-6631(99)02410-1].
