Air Tabs Installed
Well I pull the trigger to and install Air Tabs on my camper. Hoping to cut the wind noise around the passenger door and reduce bugs. We will see how it works. ART

Vortex generators create turbulent flow. Turbulent flow is much better at sticking to surfaces and following curves, hence (the theory is) will close in behind a blunt shape more quickly, reducing the size of the separation bubble behind it. So they should themselves cause a little extra drag, but the reduction in drag due to the smaller separation bubble you are dragging behind more than makes up for it. That's the theory.
Same reason golf balls have dimples. I love the episode of Myth Busters where they dimple a car and compare fuel mileage with vs. without dimples. One of my favorites for sure.
I'm going to look into this air tab thing a bit more. Thanks for posting!
