Vortex Generators / Hmmm Airtabs

[ZugyNA]

I've studied the vg thing and have installed some.

I'd have to guess that the ones on the roof are in an area where the boundary layer has already separated to some extent....probably reducing their effectiveness. Maybe try moving them forward about a foot?

The ones on the deck lid are at a place where the air has pretty much separated for sure from the sharp drop at the window.

I had some on the roof of a hatchback with less slope...slightly different design of vg though...similar to the Mitsubishi kind. Found that silicone caulk is best for permanent mounting.

Good to see the accurate testing....and some positive results.


Here is a similar car with similar flows:

Notice that he has his version of vg mounted the other direction? This plane cruises at around 60 mph.
