“…Detailed discussions on these nonuniform distribution and particle dynamics near shocklets are given in Ref. [8]. In summary, a variety of unique small-scale features in highly compressible turbulence against the statistical properties of incompressible turbulence were revealed by our previous studies.…”

“…Near shocklets, the acceleration magnitude decorrelates even faster than components, since shocklets only induce large acceleration in the normal direction but has a minor effect in the tangential plane. We also investigated the dynamics of inertial particles being passively convected in CIT [8]. Heavy and light particles respond differently to shocklets; thus, they exhibit very different nonuniform distributions.…”

“…In this paper, we will review some recent progress on compressible turbulence from the authors' group, including fundamental studies on compressible isotropic turbulence (CIT) and an engineering model of a constrained large eddy simulation (CLES) for wall-bounded turbulent flows. Details can be found in our recent papers [2][3][4][5][6][7][8] for the CIT and [9][10][11][12][13][14][15][16][17] for the CLES method and its validations and applications, respectively.…”

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.

“…In addition, a numerical hyperviscosity formulation is proposed to remove the alias er-ror associated with the CC scheme without compromising its numerical accuracy. With this hybrid scheme (hereafter we call it Wang's scheme for short), the authors made a thorough study of subsonic isotropic turbulence, including but not limited to effect of shocklets on the velocity gradients [40], effects of local compressibility on the statistical properties and structures of velocity gradients [41], scaling and statistics of velocity structure functions [42], and shocklets-particle interaction [43], to name a few. For recent progress in this direction, please see the review of Chen et al [44].…”

This paper presents an extension work of the hybrid scheme proposed by Wang et al. [J. Comput. Phys. 229 (2010) 169-180] for numerical simulation of subsonic isotropic turbulence to supersonic turbulence regime. The scheme still utilizes an 8th-order compact scheme with built-in hyperviscosity for smooth regions and a 7th-order WENO scheme for highly compression regions, but now both in their conservation formulations and for the latter with the Roe type characteristic-wise reconstruction. To enhance the robustness of the WENO scheme without compromising its high-resolution and accuracy, the recursive-order-reduction procedure is adopted, where a new type of reconstruction-failure-detection criterion is constructed from the idea of positivity-preserving. In addition, a new form of cooling function is proposed, which is proved also to be positivity-preserving. With a combination of these techniques, the new scheme not only inherits the good properties of the original one but also extends largely the computable range of turbulent Mach number, which has been further confirmed by numerical results.
