FLUENT will solve this in a moving frame of reference. This is a good simplification, because with it we don't have to deal with moving mesh. (yet! Keep checking for future tutorials on that!)

Note that we're solving a turbulent problem, and we will assume k-epsilon model with default FLUENT values 

Boundary Conditions

The boundary conditions are:

• Inlet (far-field): constant velocity in the x-direction of 10m/s, with turbulent intensity of 5% and turbulent viscosity ratio of 1.
• Outlet (far-field): absolute pressure of 101325 Pa, or 1 atm, with same turbulent parameters as above. 
• Blades: wall, so no velocity. (No-slip condition).
