I have hydrokinetics turbine simulation with Ansys fluent 6 DOF 19.2. Everything is working well, the turbine rotates because of the water stream. I can calculate the torque and Force of the turbine. My question is, how to calculate the RPM? 

Best Regards

Have a look in the tutorials, they'll show you where everything is. Click on "help" in Fluent at 2019Rx onwards.

Assuming you set up the axis for the fluid, check angular velocity and/or circumferential velocity. For the latter you'll need to remember to correct for radial position.

Hallo Mr. Rwoolhou,

many thanks for the answer. Unfortunately, I am new with Ansys and I am not sure about the axis setup and where to check the angular velocity, could you please show me?

best regards,

finally I changed into Ansys CFX which is more easier for me solving the problem, thank you very much
