While researching drag reduction for busses and trucks I came accross the following drawing in
Piechna's book:
It was used to illustrate the effects of rounding leading edges and using
air deflectors, but the author mentioned that the reduction of drag by using a "bubble" in the turbulent area would be outweighed by the penalty of increasing frontal area. A much better way to get the desired shape would be to change existing angles without increasing FA, though this is not always an option.
Of course, what is true for box-shaped busses may not be so for smaller (different Reynolds number) cars with better aero. A-B-A testing?
