Abstract

The near-wall resolution requirements to accurately resolve the boundary layer in wall-bounded flows remains a pacing item in large-eddy simulation (LES) for high-Reynolds-number engineering applications. Chapman (1979) and Choi & Moin (2012) estimated that the number of grid points necessary for a wall-resolved LES scales as Re^(1.9), where Re is the characteristic Reynolds number of the problem. The computational cost is still too high for many practical problems, especially for external aerodynamics, despite the favorable comparison to the Re^(2.6) scaling required for direct numerical simulation (DNS) where all the relevant scales of motion are resolved.
