 湍流的重整化群(RG)分析,主要基于KG威尔逊的粗粒化程序,导致湍流系数和模型的暗示性结果。该方法在湍流中的应用源于许多作者的贡献,并在1986年V Yakhot和SA Orszag的工作之后受到广泛关注。Yakhot-Orszag方法涉及基本的重整化群尺度去除过程,以及额外的假设和近似;他们的分析在这里进行审查,试图澄清这些近似。一些相关的和随后的文献的讨论也包括在内。根据M Avellaneda和AJ Majda的工作,将该方法的一个简单版本应用于模型被动标量问题,其中可以看出,在某些情况下,RG方法可以恢复精确的结果。
▪ Abstract The renormalization-group (RG) analysis of turbulence, based primarily on KG Wilson's coarse-graining procedure, leads to suggestive results for turbulence coefficients and models. Application of the method to turbulence evolved from the contributions of many authors and received widespread attention following the 1986 work of V Yakhot and SA Orszag. The Yakhot-Orszag method involves the basic renormalization-group scale-removal procedure, as well as additional hypotheses and approximations; their analysis is reviewed here with an attempt to clarify those approximations. Discussion of some related and subsequent literature is also included. Following the work of M Avellaneda and AJ Majda, a simpler version of the method is appplied to a model passive scalar problem wherein it is seen that, in certain cases, the RG method can recover exact results.
