Low-Reynolds number simulation
I try to reproduce a low-Reynolds number simulation in Fluent:

airfoil NACA2415 Reynolds number 200000 alpha 2.0 degree.

I use for validation the UIUC airfoil data base.

For starting the simulation I need the free stream speed. My question is if it is correct to extract the speed from the Reynolds number imposing constant density and viscosity:

V=Re*miu/(ro*chord), where:

Re=200000; miu=1.7894e-05; ro=1.225 and the chord=1.

For simulating an incompressible low-Reynolds flow it is sufficient to have the same Reynolds and incidence ?

Thanks in advance.
