Truck Aerodynamics - What & Why? - Aerodyne

The yellow and red are higher wind velocity areas, green is relatively low, blue is very low. You can also see the vacuum at the back of the box from this too.

This paper discusses the aerodynamics of several different configurations of bus:

In several of them, the low velocity area over the roof is pretty clearly visible (esp. Figures 2, 4, and 6).

Interesting stuff. Thanks for posting it. Still glad I used screws tho!
