Transition flow in a heat pipe

I am simulating (using Fluent 12.1) a flux of oil in a heat pipe. Obviously the turbulence of the fluid influences the heat flux generated. I have Reynolds = 1911, which turbulence model is the best to use in this case? Should I use the laminar model? If no, which transition model is the best for my application? I hope I've been clear.
Thank you all!

you have to make a sensitivity analysis between laminar/ and low-Re turbulence model.
I would use low Re turbulence models:
SST with Low-Re correction, or better the transitional ones in Fluent. There other k-epsilon based turbulence models which are low-Re ones (access over TUI)
your yplus hast to be in the viscous sublayer around 1-max 5 expansion in the boundary layer 1.1-1.2
