有前辈用特定能谱来生成二维湍流场吗
我也在琢磨OpenFOAM中的各向同性二维湍流结构
@东岳 https://www.zhihu.com/question/30563547 李老师,我是根据这几位前辈的建议来学的。不知道您那有没有其它书或建议?
三维的在OpenFOAMv系列里面就可以实现 see Decay of homogenious incompressible isotropic turbulence tutorial: decayIsoTurb,你可以直接研究那个代码,目前我打算生成二维的,也在学习,手头没有一针见血的资料给你

我需要一个OpenFOAM的2D的湍流初始场,这个是我要复现的数据,如果我弄出来我会分享下我的算例,如果你看到比较透彻的公式,你可以直接植入,也可以分享给我我看看植入进去试试
Scalable Tools for Generating Synthetic Isotropic Turbulence with Arbitrary Spectra这篇文章你看了么,参考第三节Algorithm写的很详细,但是是三维的没说怎么做二维的

我看的比较慢,有些基本概念还不太清楚。
