Since the streamlines are only going to reflect the mean velocity field you are not going to get a lot of useful information concerning turbulence. The most straightforward measure is to plot the...

I would be very surprised if the flow relaminarizes - you are carrying turbulence into the fluid from the upstream, and the Re of the fin sections is going to play a significantly reduced role in...

One question - you say that the flow moves through a duct where the flow is turbulent and then into a region with some fins where the flow is then laminar. What is driving the relaminarization of...

I don't know anything about CFX (I use in-house tools for CFD), so I can't really contribute a lot to your search other than consider the usual suspects - y+ spacing, wall function behavior if you're...

The only meaningful generalization that I have ever developed is that CFD is still essentially binary when it comes to transitional flows - it really only works well if the flow is laminar or...
