does any one knows or dimples work in round moving object like a wheel

RE: dimples
RE: dimples
and at wich speed does it works then
and when wheel comes in a yaw angle? does it still work
if the layer becomes more turbulent it create more force right or am i wrong
since like a cyclist want the air not to be turbulant
so what you are saying turbulant air make you faster
i thought it make's you slower??

RE: dimples
I don't have any formula to back it up, maybe somebody else has more time to look something up for you?
Somewhere cd-values must be available for wheels with or without dimples.
RE: dimples
Once you have a cd-value for the wheel with dimple that you want to study, you can find the total drag with the following formula:
Drag = cd * S * .5 * ? * V^2
S = wheel reference area
? = air density
V = airspeed
But I suppose you knew this already.
RE: dimples
the problem that is till have that the dimples move or up or down depends where you look on a wheel
i my mind it only create's more drag force
so that why i look at the formula not only as cd figures that meaby a compagny published to promoto there dimples wheel

Some more on dimple aerodynamics
