TL;DR: In this paper, the authors proposed a method that allows for the log-layer mismatch to be removed, thereby yielding accurately predicted skin friction, by considering the behavior of turbulence length scales near a wall.

TL;DR: The results indicate that the WENO methods provide sharp shock profiles, but overwhelm the physical dissipation, and the hybrid method is minimally dissipative and leads to sharp shocks and well-resolved broadband turbulence, but relies on an appropriate shock sensor.

TL;DR: In this article, the authors provide a brief introduction to the near-wall problem of LES and how it can be solved through modeling of the near wall turbulence, and the distinctions and key differences between different approaches are emphasized, both in terms of fidelity (LES, wall-modeled LES, and DES) and in the terms of different wall modelled LES approaches (hybrid LES/RANS and wall-stress-models).

TL;DR: In this paper, a set of direct numerical simulations of isotropic turbulence passing through a nominally normal shock wave is presented, and the instantaneous structure of the shock/turbulence interaction is examined using averages conditioned on the instantaneous shock strength.
