Reynolds stress calculation from k-epsilon model
Hi I got a result using k-epsilon model. I am trying to calculate Reynolds stress from the result. How can I get the x, y, z fluctuating component from kinetic turbulence energy variable?

You'll need to run with the reynolds stress model.

Re: Reynolds stress calculation from k-epsilon mod
Hi,
You can estimate the Reynolds stresses from a k-e result. You assume all the Reynolds stresses are equal then the two turbulence parameters fully define the turbulence. Look in any turbulence textbook for the derivation (Turbulence modelling for CFD by Wilcox is the one I use). Glenn Horrocks |
