OF的湍流模型怎么改湍流普朗特数？

[程迪]

Prt默认似乎是1.0，我想改成0.9，看了一下SA模型相关的代码，感觉很迷糊，狗X的OF1612+里有eddyViscosity和EddyViscosity两种涡粘性，还有turbulenceModel和TurbulenceModel两个文件夹。感觉里面关系比较诡异。

没用过1612+，不过openfoam4中turbulenceModel是在TurbulenceModel里面的。不是平行的关系啊。

@赵一铭

但是这个就很诡异，OF的命名逻辑一般是没有大写开头的词...

而且你去搜也不会有大写的TurbulentModel类。

... as part of the development of multiphase turbulence modelling, a new single, general templated turbulence modelling framework was created that covers all four of the combinations. The framework can be found in $FOAM_SRC/TurbulenceModel (upper case “T”) and includes the incompressible, compressible, phase-incompressible and phase-compressible options including support for laminar, RAS and LES simulations with wall-functions and other specialised boundary conditions.

额，看错了，木有EddyViscosity, 只有EddyDiffusivity和eddyViscosity。

@程迪 程老师您好，请问您知道如何把Prt定义成某个表达式吗？
