对最近提出的大尺度结构对近壁湍流影响的准定常准齐次(QSQH)理论进行了展望。本文重点讨论了滤波器的选择,它定义了大规模结构。它给出了一个简单的概述QSQH理论,讨论了过滤器需要区分大尺度和小尺度,和QSQH理论的准确性的相关问题,描述了使用QSQH理论所需的探针,并概述了从中等到高雷诺数的近壁湍流的特性外推的过程。
An outlook on the recently proposed quasi-steady quasi-homogeneous (QSQH) theory of the effect of large-scale structures on the near-wall turbulence is provided. The paper focuses on the selection of the filter, which defines the large-scale structures. It gives a brief overview of the QSQH theory, discusses the filter needed to distinguish between large and small scales, and the related issues of the accuracy of the QSQH theory, describes the probe needed for using the QSQH theory, and outlines the procedure of extrapolating the characteristics of near-wall turbulence from medium to high Reynolds numbers.
