hi all

I have a question with my project in fluent.
what's the best turbulant model for a wind tunnel that have a vertical tube inside analysing the heat transfer coefficient
(3e04<Re<2e05 internal folw)
Is there any paper that investigate the turbulant models in this case?

I would recommend sst-komega and ensure that the y+ of the mesh at the wall of the cylinder is less than 1. Ignore the Low-re option that you can select in the sst options. By default this is off.
