The near-wall resolution requirement to accurately resolve the boundary layer in wall-bounded flows remains one of the largest obstacles in large-eddy simulation (LES) of high-Reynolds-number engineering applications. Chapman (1979) estimated that the number of grid points necessary for a wall-resolved (WR) LES scales as N_(WR) ~ Re^(9/5), where Re is the characteristic Reynolds number of the problem. A more recent study by Choi & Moin (2012), using more accurate correlations for the skin friction coefficients, concluded that N_(WR) ~ Re^(13/7), which is far too expensive for many practical engineering applications and not very different from the N_(DNS) ~ Re^(37/14) scaling required for direct numerical simulation (DNS) where all the relevant scales of motion are resolved.
