Anisotropic turbulent heat flux.

Golaselo · October 12, 2021, 04:40

Hello everyone,

I need to include anisotropic turbulent heat flux in my case (2D flow in pipe). Equations in Ansys are too general to do it without modifications. Can anyone help me to write UDF/UDS? I am a bit beginner in CFD world, but my proffesor told me that I have to do it. I would appreciate any help or maybe paid service? Below I send article that is exactly similar to my case.

It seems that the paper actually has everything you need to do your exact task. Probably I would not discard the first method based on the source term, but the proposed solution is certainly simpler.

All you need to go from the paper to the implementation is actually knowing Fluent and UDFs. If you don't have this knowledge and you can't (or don't want to) acquire it, your chance is indeed someone else doing it for you. But (just like the proper forum for this post would have been the Fluent one), the proper place to ask is the freelancer forum

Have you figured out how to implement this in energy equation?
