Hi there,

I want to understand the meaning of those terms used from OpenFoam like for example RAS turbulence.
The following is written in the userguide:
RASModel
uses Reynolds-averaged stress (RAS) modelling; But what does that mean? Does someone know where I can find the explanation to that?
under this link there is a list, but also no explanation of what is ment with for example: kEpsilon
Standard high- model

In the RASproperties there are lises many keywords like kEpsilonCoeffs. Where can I find their meaning?

Regards,
tH3f0rC3

Hi,
You are asking basic questions about turbulence models. Look up in search sites and you will find a lot of information about this.

Aaaaaaah, OK.
Thank you. I thought this would be names created for turbulencemodels from the one who programmed this files.
But these files are named to their scientific background.

Thank you!
