Rotary woofer simulation

Hello.

I am trying to simulate this recently developed rotary woofer:
www.rotarywoofer.com/
www.jpark.us/pubs/JASA_125(4)_RotaryWoofer_2009.pdf

My main goals are to find out air flux and energy flux rates going through it, as a function of rotation velocity and signal frequency.

Is that possible?
I reckon simulating an axial fan is probably the first step to take, but I get a bit lost in comsol even for that.
Any tips or directions?

Thanks
