“…It is clear from Fig. 16a that the mean velocity profile (following van Driest transformation [62,63]) given by CLES agrees very well with the log-law profile, while the buffer layer from the LES-SM strongly deviates from those obtained by CLES and DES. Furthermore, an apparent super buffer layer is observed in the mean velocity profile from the DES, as reported in the incompressible cases [10,57,58].…”

In this paper, we review some recent studies on compressible turbulence conducted by the authors' group, which include fundamental studies on compressible isotropic turbulence (CIT) and applied studies on developing a constrained large eddy simulation (CLES) for wall-bounded turbulence. In the first part, we begin with a newly proposed hybrid compact-weighted essentially nonoscillatory (WENO) scheme for a CIT simulation that has been used to construct a systematic database of CIT. Using this database various fundamental properties of compressible turbulence have been examined, including the statistics and scaling of compressible modes, the shocklet-turbulence interaction, the effect of local compressibility on small scales, the kinetic energy cascade, and some preliminary results from a Lagrangian point of view. In the second part, the idea and formulas of the CLES are reviewed, followed by the validations of CLES and some applications in compressible engineering problems.

“…Nevertheless, validation of STBL are limited by less available experimental data compared to subsonic or incompressible turbulent boundary layers. Few simulations including DNS and LES had been reported in the literature on supersonic boundary layers and channel flows [17][18][19][20][21][22]. The effects of wallcooling/heating on turbulence structures, compressibility and turbulence scaling are poorly addressed and the literature of STBLs with heat transfer is not abundant.…”

Abstract. The paper presents near-wall scaling in incompressible and compressible flows. It concentrates on flows with streamwise pressure gradients which render traditional scaling inapplicable. For incompressible flows a scaling for the velocity profiles is introduced based on both the friction velocity and the pressure gradient. For compressible flows a scaling is developed for the velocity and the temperature. This scaling is based on wall friction, pressure gradient and wall heat flux. We define two new parameters α and β where α defines a measure for the ratio between wall friction and pressure gradient and β defines the ratio between wall heat flux and pressure gradient. For zero pressure gradient flows the traditional scaling is recovered. A priori tests are performed by means of Direct Numerical Simulations (DNS). The compressible scaling is analyzed on channel flow with non-adiabatic walls and adverse pressure gradient. The incompressible scaling is analyzed on channel flow with periodic hill constrictions. Finally a wall model based on the new scaling is tested a posteriori by means of Large Eddy Simulation (LES).
