摘　　要：综述了可压缩流体中湍流流动的研究现状，重点针对快速大变形情况下湍流的特性进行论述．讨论了可压缩湍流中扰动的三种模态和能量的转换与平衡关系，对快速畸变理论和可压缩湍流的数值模拟方法作了简要介绍．A review of research status of turbulent flows in compressible fluids is presented,with emphasis on the turbulence behavior under rapid distortion and large strain. The threemodes of disturbance fields and the energy transform and balance in the compressible turbulenceare discussed. A brief introduction to the rapid distortion theory and to the numerical modeling ofcompressible turbulent flows is given.
