pisoFoam turbulent case looks like laminar case
 
Hi all,

I am using pisoFoam to simulate a simple turbulent flow through a pipe. I have used 2D axisymmetric wedge to perform this simulation. The pipe dimensions are Radius = 0.1m and length = 8m. Fluid used is water. Inlet velocity is 50m/s which makes the Reynold number 10^7.

The problem is that the flow looks like a laminar flow after running the case.

Can you point out what is wrong?

Also, if i want that my pipe has surface roughness then should i use nutkroughwallfunction?
