Quantification of resolution

Mesh resolution

Provide wall resolution in wall coordinates, both normally ("y+") and tangentially ("x+", "z+"). Evaluate typical turbulence length scales (Taylor microscale, Kolmogorov) and compare to local resolution. In case the case presents homogeneous directions, one could also provide spatial correlations between the velocity components. If possible provide computed temporal spectra at selected locations and relate to spatial resolution e.g. by using Taylor's hypothesis.

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.
