The aerodynamic test "buck"

Looks stationary.

LOL

Sorry, stupidly worded question.

Although the wheels are shown stationary, is the airflow calculated with rotating wheels?

Depending on how you shape the sides of the wheel spokes could the wheels work as fans, forcing air outwards or drawing it inwards - or neither - if you have an even number of spokes and alternate their shape?

Would this do anything useful or would the effect be purely secondary - e.g helping reduce the build up of dirt on the alloys or creating harmonics which compliment the pitch of the motor?

I meant that the data look like the wheels are stationary.

Yes I think you're right. How odd that the aerodynamic effect of rotating wheels isn't taken into consideration.

I guess the software can only model airflow over static obstacles.
