OpenFOAM原始的Ck、Ce的值是哪里搞出来的你知道么?
我找了几个原始文献(主要是Lilly1967,DearDorff1970,以及Moeng and Wyngaard1988),里面讨论了这个Ck Ce的东西,我没太细看。不过看起来这个值是推导出来的,要满足。不过Cs的值都不一样。我再看看。
最近没细看这个玩别的去了。我参考Spectral analysis of large eddy simulations of the convective boundary layer昨天晚上推了个八九不离十。这个ck ce是符合湍流能谱的一个常数。这是前人已经做过的工作。没法写英文了。我以为别人没玩过这个。哈哈

@coolhhh 太细致了!!!
