This serrated edge doesn't extend as far down as the leading edge. The only thing I can think that these do is to break up the boundry layer on the wing. Usually extra surfaces and bumps just cause the boundry layer to get bigger though. Quite the conundrum.

Perhaps it makes the DRS effect slightly stronger?

Creating mini-vortexes to keep the airflow attached?

yup that's right

Putting this things on the glider wings is well known for atleast two decades. We call it turbolator. It is a zig-zag tape. If put correctly in the area of boundary layer separation, it prevents abrupt transition from laminar to turbolent airflow. Performance of the glider gets a bit better.
Last eight, ten years some people started to R&D so called deturbolators. These devices make wing ofa glider with wortmann profiles 15 to 18% more efficient, meaning better L/D at higher speed for given glider.
If you are interested go and get some info on this page:

Strangely gliders have it also on the under-side of the wing. Almost ripped that zig-zag tape off when polishing a Duo-Discus yesterday. I know it is off topic. But what's the use on the underside?

Strangely, but abrupt transition from laminar to turbolent airflow has much bigger effect on performance when happening on lower side of the wing. I dont understand this. Try to read some about that on the link I posted abowe.
Sorry for of topic.

They are placed very low in the boundary layer and with is being so low it wouldn't create any useful vortices in the traditional sense.

Yes they help keep flow attached but it seems more by my initial thought of breaking up the boundary layer.

Maybe the laminar flow "superaccelerate" over microvorteces without deattaching.

You won't get laminar flow in its actual form with such a heavily cambered wing as in the F1 rear wing.

Is it possible that this efect only is in use when DRS is on and the flap is lifted? Is not then camber of upper flap lot less?

[mrluke]

Could it be to help the transition from DRS open to closed?
