Shell makes an oil called something like 'Ondina',it's used in smoke generators,non-toxic.Just needs to be heated while soaked into some sort of matrix like steel wool.
Smoke bombs or smoke grenades would work.Not getting arrested would be the challenge,unless you could quench them on demand.
If you ever got rain,someone could film you from long distance as you pass in front of a dark,high-contrast background ( like a row of trees ).It really shows the water entrained within the wake.I get to see 18-wheeler wakes this way when its wet.

I'll look around, I bet I can find something that will work without breaking the bank. I just want to reproduce something similar to the photo of the smoke stream in front of the Calibra in Huchos book on page 183. That would take a huge amount of guesswork on so many of these shapes.
At this point I'm interested in figuring out the shape of the front and rear wheel fairings, and just seeing how it flows under the RV with the pans in place, especially around the rear axle housing.
I like the smoke bomb idea also. Put one in place under the hood, figure out how to set it off from the driver's seat, set if off when you get up to highway speeds, and film the bellypan area with my camera system to see where it comes out and in what volume. I could hook up four cameras to a quad mobile DVR, that would be awesome.
I think I've just become an aero nerd.
Hmmm, maybe that will be the next action figures - Aero Nerd! OK, maybe not.
