Searching on that doesn't turn up any obvious thread. Adding 'vortex' doesn't help.
It seems like treating only the top one of the four rear sides can't be too effective. Experiments with blown slots (

pg 67: Generate lift, reduce trailer weight 15% = more efficiency? Uh-Oh. How much more of this article is suspicious or worse yet, garbage?

That's Englar. Active aerodyamics via pumped air. He found he could effect plus/minus drag and lift by valving the slots on the four rear sides; All on to go, sides off to stop, top off (I think) for lift and bottom off for downforce (or vice versa). |
vBulletin doesn't handle links inside quotes very well, I give up.
Different effects for the different sides, all four on for least drag, sides and bottom only for lift; it's not clear what doing the top on only would do.
