How would I calculate (or simulate) this? I am only interested in the aerodynamic drag caused by the surface moving, not any other forces.

As far as I know, the only variables needed are the drag coefficient, the air density,the radius, and the angular velocity of the disk. After that I am pretty lost.

The question is very unclear. What do you mean "spin a disk along its diameter"? Do you mean there's an axis of rotation running from one edge of the disk to the other? Do you mean air hits one side of the disk and not the other to make it spin? Maybe you could clarify the question and/or give a concrete example. – Mike Dunlavey Dec 2 '12 at 1:25
