Air-Flow Simulation of a Savonius Rotor
I have designed a Savonius Vertical Axis Wind Turbine on a CAD programm. Now I want to test it on CAEDIUM to simulate the airflow, the pressure, the forces and the moments. I have defined an flow-volume and a inlet/outlet, the surfaces are walls etc. The simulation of the airflow and the pressure works very well, but I have problems with the forces and the moments. The results are far away of which is possible. Also I want to know if there is any possibility to simulate that the Savonius Rotor rotates because of the airflow. Are there any compareable examples?
I am grateful for any little help,
