I was wondering about this for a project of mine. With a cycle fender that moves with the tire, you could get get the gap near zero. Is there an optimal gap for the least drag?

I'm thinking about the airflow strictly within the fender. With the fender stationary and the tire surface moving at high speeds I would guess that getting the gap too small could mess up the establishment of boundary layers and increase drag. Or could this disruption reduce drag?
