The wall-normal position in pipe and channel flows at which viscous and turbulent shear stresses are equal

Research output: Contribution to journalArticle

Abstract

The Reynolds number dependence is estimated for the wall-normal position at which the turbulent and viscous shear stresses are equal. For large Reynolds numbers, this position coincides with the peak location of the mean momentum transport terms due to turbulent and viscous action. Experimental data are used to corroborate the results and assess some quantitative details.
