Turbulent flow in a concentric annulus with heat transfer and magnetic field

Hi all,

I am currently modeling the magnetocaloric effect inside a horizontal concentric annulus to model a magnetic refrigeration system. However, after some investigation I saw that the flow is pretty turbulent and shows oscillatory behavior. Therefore, I want to change my current physics (laminar flow, heat transfer) to turbulent flow.

I saw in Comsol 5.3 that there are several models to choose from. Does anyone have any idea which one might provide the best combination of accuracy and robustness regarding my system?

Many thanks!

Evthimios
