or the lack there of. it would seem to make perfect sense. Anyone know of any experiments done with it? I wonder why they aren’t incorporated…
Recently was thinking of the same thing. Aero helmets are now designed to be streamlined to prevent the separation of boundary layers. From what I understand, trip wires (and dimples) are more used for blunt objects that are inherently not streamline and have early boundary separation creating turbulence and vortex shedding early.
It has seemed that the cycling industry has focused on making items stream line rather than induce turbulent flow with a tripwire to delay boundary separation. However, the human body is not very stream lined. Yes we have aero helmets to make our spherical shaped heads more like a teardrop, but what about our cylindrical legs. These are rather blunt and have rather large profile to the wind. Maybe keeping legs unshaven would act as dimples or tripwire and actually be more aero rather than shaven legs!
