A novel method is proposed that allows accurate estimates of the local wall shear stress from near-wall mean velocity data in fully developed pipe and channel flows. DNS databases are used to demonstrate the accuracy of the method and to provide the reliability requirements on the experimental data.
Many technically relevant Β―ows are wall-bounded Β―ows at high Reynolds numbers. The knowledge of the near-wall behaviour of turbulence is important for the correct modelling of these Β―ows. The inΒ―uence of the Reynolds number on turbulence quantities results from the imposed boundary conditions at the
