[Other] Explain about the coefficients in the kOmegaSSTLM turbulence Model

ht2017 · April 2, 2018, 03:04

Hi everyone,

Now, I am working with kOmegaSSTLM turbulence model in the OpenFOAM but I have a question want to everyone explain. In this turbulence have the 6 default LM coefficients is "Ca1,Ca2,Ce1,Ce2,Cthetat,sigma theta". So that How to do you have the value of all coefficients and what is the meaning of the coefficients. I have read the three references which are the concerning this turbulence. this is:
- langtry,R.B.,& Menter, F.R.(2009). correlation-based transition modelling for unstructured parallelized computational fluid dynamics codes.
- Menter F.R., Langtry, R.,& Volker,s.(2006) transition modelling for general purpose CFD code.
- Langtry,R,B.(2006).
A correlation-based transition model using local variables for unstructured parallelized CFD codes. PhD. Thesis, University Stuttgart.

But I also understand the meaning of all coefficients and the range of them.

So if who can know about the coefficients above or have the range of value the coefficients. pleases Let's me know. I am very grateful for that.
Thank you so much.

As far as I understand. They are just correlation parameters that were obtained by fitting experimental results.

I wrote a paper on the coefficients in the model and how they were fitted
