Default Turbulence Model and limitation to Reynolds number

qascapri is on a distinguished road
I am modeling heat transfer in a two-pass trapezoidal channe using Fluent. The Reynolds number at the inlet is 9400. I used low-Re k-epsilon model, RNG k-epsilon model, realisable k-epsilon model, standard k-omega model and SST k-omega model of Fluent to model turbulence. The comparison of numerical results with experiemnts shows that low-Re k-epsilon model is most accurate. The litrature on the other hand shows that SST k-omega model is the best. What can be the reason that I am not coming to the same conclusion as researchs have shown in the literature.
Is there any limitation with respect to the Reynolds number in the choice of a particular turbulence model?
