not getting turbulent flow trajectories in a simple flow system

I am trouble getting any turbulent flow trajectories in a model of water flow through a cylindrical tube, with an inlet volume/pipe diameter that gives a Reynolds number that should easily be in the turbulent range. I selected "turbulent only" in the simulation wizard. Yet, when visualizing the flow trajectories for velocity, I only see what appear to be laminar flows (in straight lines parallel to the long cylinder axis). This happens regardless of whether I model the inner pipe surface as a real wall or ideal wall.

 

Shouldn't I be seeing eddys/non-laminar flows if well above the threshold Re number?
