Quantification of resolution
Mesh resolution
A mesh resulting in approximately 250 million degrees of freedom (DoF). With a stretched grid, the maximum grid resolution in the duct centre is reported at , , . Correspondingly, the wall resolution (in terms of the first grid point) is reported as , in the spanwise and normal directions, respectively, is used.
Solution verification
One way to verify that the DNS are properly resolved is to examine the residuals of the Reynolds-
stress budget equations. These residuals are among the statistical volume data to be provided as
described in Statistical Data section.
