Default Modeling marine propeller in fluent

Hi, I'm trying to simulate flow around a propeller. The propeller is rotating, so I'm fixing it and rotating water instead of propeller. I'm using single rotating reference frame. I don't know if this is cgrrect, results are not OK. How big should be domaind for a propeller D=0.3048m My is r=6m, 3m upstream, 10m downstream.

If anybody know how to do this, please help. Thanks Lukasz

You have to use at least multiple rotating frames. If you want to calculate the interaction between the ship hull and the propeller you have to use sliding mesh.

I don't know much about Fluent but if he only simulates a single propeller and does not want to take into account the interaction effects between the propeller and the hull, an attached blade frame can be used, and the flow around a propeller can be regarded as a steady flow.

You want to check out the research done by Moustafa Abdel-Maksoud on CFD propeller modelling. There's lots of references on the web.

I'm modeling only the propeller, I got problems at advance coefficient about J=1.1 and higher.
