Abstract:

The near-wall scaling of mean velocity U(y) is addressed for the case of zero skin friction on one wall of a fully turbulent channel flow. The present DNS results can be added to the evidence in support of the conjecture that U is proportional to sqrt(y) in the region just above the wall at which the mean shear dU/dy = 0.
