Guys i have a stupid question, usually in fluent when we have a high Reynolds number we use a turbulence model like k-epsilon, k-omega ecc.. and the equations that we are solving are the RANS.So, when we don't use the turbulence model the governing equations are still the Reynolds averaged NS, or the method is different? If not what are we solving, just a discretization of NS? thank you in advance.

The governing equation is the same. Laminar is just RANS without any eddy viscosity.
