中文摘要：

在这份报纸，我们在作者组进行的可压缩的骚乱上考察一些最近的研究，它在为围住墙的骚乱开发抑制大旋涡模拟(CLES ) 上在可压缩的各向同性的骚乱(市民) 和应用研究上包括基本研究。在第一部分，我们实质上以最新建议的混合 compactweighted 开始为被用来构造市民的一个系统的数据库的市民模拟的 nonoscillatory (WENO ) 计划。用这个数据库，可压缩的骚乱的各种各样的基本性质被检验了，包括统计并且从一个 Lagrangian 观点的可压缩的模式， shockletturbulence 相互作用，小规模上的本地压缩的可能性的效果，动能串联，和一些初步的结果可伸缩。在第二部分， CLES 的想法和公式被考察，处于可压缩的工程问题由 CLES 和一些应用程序的确认列在后面。

英文摘要：

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 con- strained large eddy simulation （CLES） for wall-bounded turbulence. In the first part, we begin with a newly pro- posed 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 interac- tion, 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 for- mulas of the CLES are reviewed, followed by the validations of CLES and some applications in compressible engineering problems.
