Those are super tiny! Wondering if bigger ones are usually used on cars because of the lower speeds or because they are usually positioned on the roof instead of on a wing. Hmmm... may have to try and speak with people who are smarter than I on this one.
Doing some quick reading, choosing the correct height of a vortex generator depends on the thickness of the boundary layer of air where you plan on placing the fins. You want the same height fin as thickness of the boundary layer. Wondering if the profile of a car creates a much thicker boundary layer over the roofline of a car than an airplane wing creates over the top of its surface. Furthermore, if these work on the top of an airplane wing, wouldn't they then work on the bottom of a car wing to increase efficiency? Can't say I have ever seen that done before...
