I just finished reading the Aerodynamics chapter in Mike Burrows' book Bicycle Design. He speaks about adding "turbulators" (airflow disruptors?) to bluff bodies, like bicycle tubing and aero-helmets, to create premature turbulent flow (at laminar type Reynolds numbers) and decrease its overall drag. He isn't clear on how large to make them (relatively speaking of course) nor does say where to put them other than a "6cm wide PVC insulating tape down the front of your fork balde." Does anyone know of some literature that explores this further? Or has anyone tried doing this on tubing? I know it's only theretical and probably doesn't have much application in the real world, but thinking about stuff like this keeps me off the streets and out of trouble.
On a lighter note. Has anyone tried the "Mohican stripe" down the front of their legs? I want to try it just to see if I can get someone to believe that there's an aero advantage and "psych" them out. One thing I won't try is that Chia-Pet looking helmet. I can hear it now... "Ch-Ch-Ch-Chia!" as people pass me left and right.
