I was wondering if it is possible to simulate turbulent flow of non-Newtonian fluids using CFX,
The material is a power law fluid which is a polymer,
The main goals of the simulation is to get the velocity profiles, Reynolds stresses (Pressure drop is also important because it supposes to be a drag reducing flow).

I have not checked but I suspect it is possible to run a non-Newtonian model with a turbulence model, but the question of whether it is accurate is another issue. There are no turbulence models widely accepted to my knowledge for non-Newtonian flows. So I would be very careful with these models and do thorough validation.
And the situation is the same for all CFD codes - it is current research to apply a turbulence model to non-Newtonian flows, so I doubt you will find anyone can do it easily.
But if you don't care about accuracy and all you want is a turbulence model and a non-Newtonian flow model then, yes, CFX can probably do it.
