Dear everyone,

i'm working on a horizontal axis wind turbine in fluent.

I have a 3 blade rotor geometry to model (without any other component interfeerence such as the tower).

I'm going to mesh a cylindrical 3D domain.

The question is: what is the correct approach to model the flow?

i'm thinking about using the functionality explained in the user's manual ''10.modeling flows in mooving reference frames'' by setting a rotation axis and a rotational speed in the cell zone conditions menu, within the fluid dialog box enabling the ''frame motion'' option.

I wonder if this is a good way of modeling my problem. In addition: what is the difference between using a mooving frame and a mooving mesh in this case?

Thank you for helping.
