For people who actually want to learn, just look at the pressure chart and the flow pattern, and draw some obvious conclusions about the relationships.
And as for the rear spoiler, just mentally place one at the back of the car (say, the same angle as the windscreen but only 1/5th as high) and then look at what the windscreen did to the pressure of the attached flow in front of it. |
I've provided a checklisted, item by item evolution of the phenomena, according to the science. Where one takes it is up to the individual.
Road testing isn't necessary. The photograph provides all the necessary information to make the verdict.
A look at the VW XL1 undergoing smoke flow testing will provide a look at what attached flow actually appears like.
