Just going off my sometime faulty memory, but I recall Aerohead or somebody saying 30-250 mph will get you your standard Cd number in testing.
And that 250-600 is it's own range, then we get into near supersonic/supersonic, and above that hypersonic speeds.
I suspect some odd things can happen between 15-30 mph depending on the shape being tested, the complexity of the forms and so forth.
I would think that at very low speeds(15-30) there would not be enough pressure built up at the front/nose to ensure attachment.
Would the air flow just rise up as if being sucked up to the heavens?
Again, I'll await Aerohead to correct any misgivings which I may have misspoken.
