Here's an early investigation for VGs on a notchback by Gary Wheeler.
Ideally,you'd have a wind tunnel at your disposal and a lot of time and money.
*there are VGs like these.
*there's also a 'wishbone' variety as well.
*the kind Subaru used on the Lancer EVO
*co-rotating VGs
*counter-rotating VGs
*angled grooves
*trip-wires
*and sub-boundary-layer-thickness 'nub' VGs
Theoretically,one would have to investigate them all,and test for quantity,and placement.The best application might include a variety of different VGs used together.
