Morelli Shape
Neil,
Since these posts I managed to track down the 1983 paper by Morelli.
And by the way aerohead, this shape is given short shrift in the very comprehensive Hucho book, which represents the mainstream thinking (not much innovation) of the auto industry.
The book on solar vehicles by Eric Thacher discusses this much better than anywhere but the Morrelli paper itself, which Thacher helped me find.
I am not at home now so I can not give the full reference, but it was a 1982 paper published in a book that was a symposium proceedings.
But as to the value of H, as I recall the Hmin shown got down to about 6 inches, but H was a variable for the testing and started at about half the maximum width.
