Getting a rotor to rotate?

Dave

Hi everyone

I have created a very basic 3 blade rotor and hub which I wish to pass water over in FLUENT. The most important thing is that I can get the model to rotate so i can look at eth effects of swirl. I have set the model up so the x-axis passes right through the centre of the hub. A box defining the fluid volume is wrapped around the turbine.

Could someone give me some basic instructions as to how to get it to do this? I read a couple of tutorials that overcomplicated things for me a bit, they told me to change the motion type of my fluid to 'moving reference frame' where i defined my rotational velocity and staed which axis it was rotating around (x axis in my case). I also set my wall boundary (my rotor) to 'moving wall' of motion type 'rotational' and left the speed at 0.

Some guidance from someone 'in the know' would be really helpful

Cheers
