Here's an interesting little wab based app, you can draw a shape and place it in a virtual wind tunnel.

I tried creating a high downforce wing, then I added a gurney flap to see the difference.

I hadn't realised that vortices detach at regular intervals, can any aeronautics guys confirm that actually happens?

Yes, click and drag in the orange box at the top, it should work in Firefox and Chrome according to the FAQs.

It uses the graphics card for the required calculations, so you may be an incompatibility there, I have an NVidia 780Ti and it works fine.
