tuft testing
David,she looks real good! I don't see any evidence of reversed flow,only 'nervousness' of the turbulent boundary layer itself,and as you say,for the #3 camera position,turbulence from the mount itself.
Nice goin'! 
PS did you ever get the DARKO video thumbdrive I mailed you?

I hope everyone is told to sweep the snow off those top vents.
I have had to teach at least five people (4 women, 1 male) that they were not going to get their defrosters to work properly unless they swept off the intakes at the bottom of their windshield.
They honestly had no concept of air flow.
This might be why people take take showers these days instead of baths. So few know that when you pull the plug it will drain the tub.  |

The state of humanity is becoming more and more appalling.
I am not shocked Anymore at people who propose I build generators on the back wheels of an ev so that it can charge the batteries to get perpetual motion. I expect it as standard.

Sorta. It would be better with the wheel rotating.
