I wouldn't really call it a turbulator. THey just call them bound vortices.

If you see an F-16 or an F-18 at an airshow on a sufficiently humid day, you'll see a chordwise vortex next to the fuselage marked by vapor when he pulls g's . That's a cool way to delay separation, but that's not what I'm talking about here. If you see an F-15 on the same day, when he pulls g's the vapor-vortex will appear on the outer half of the wings, right behind the leading edge and almost parallel. THe F-15 wing was designed specifically to let that vortex build there and delay stall. Sometimes you can see a spanwise vortex somewhere around the slats on the other two types as well.
