I'm setting up my 2D simulation process for aerodynamic profile, and thinking about the turbulence model I came across a question. The conditions are as follows:
U = 12 m / s
c (chord length) = 0.575 m
operating at Standard air 20 ° C
And calculating the Reynolds number for this flow, Re = 470000.
So I decided to use SA turbulence model, k-epsilon Realizable and SST k-omega.
According to the literature, for external flows, around a Reynolds number of 500000 we have a turbulent flow.
So, it gave me a doubt, which would be more correct: to use these models in which I quoted or some model of transition?
Thanks for opportunity!

I recommend carry out a sensitivity analysis an compare the results to a transition model. You can start by using the intermittency transition model (3-Eqn model)
