Dear all,

I try to compare measurements of fully developed pipe flow with different low-Re turbulence models (from Fluent).
So I found some nice data here:
http://www.princeton.edu/mae/people/...e-data/mckeon/
and used the Re=74343 data set.

In my simulation I just took a short piece of pipe with periodic boundary conditions. I normalized all data, that it becomes U=1 in the middle of the pipe.
This is what I get:

To be honest: I thought that these models work much better for such a simple "standard" problem. What do you think? Is this the best I can get, or am I probably doing something wrong?
