K-e in a laminar flow - what happens
 

I was wondering. When doing a turbulence calculation using e.g. K-e or RSM, what happens in the regions of the domain where the flow is laminar?

Will the model impose some false turbulence, or???

Cheers, Christian

Yes. The turbulence's production is only driven by the velocity gradients. The destruction of turbulence is epsilon. So there is no reason for the turbulence to collapse in the "laminar" regions.

hi, did u find ur answrer or u still need more information. if yes then let me know. i have got good material on t his topic .

be happy and enjoy

Dear frined, I wanted more information on this can you...? eagerly waiting for your reply.. bye

Sylvain's answer is satisfying, but I am interested in background material if you have some.

I am also in need of some matrial in that area. Nauty professor should give some idea!.. bye
