an interesting point of view (wool tuft testing video)
for the title of this thread, I have been insiperd :D

so, I have testing the rear end (declidt) of my car using famous wool tufts.
After to have numbered (for to help the interpretation) the wool stufts, and photographed the details, I have fixed the camera in the seat passenger

and I have measured the position of extended wool stuft

two pics below, they evidence that the extended sool stuft is under the ipotetical line of roof-declidt.
You can see that the extended wool stuft is in turbolent area...the famous buble it describet in this topic :

Looks pretty good. Hard to tell if #6 and #13 are not so great, or just an unlucky picture.

yesss, you have reason....It is necessary a second camera :(
Not only: after the test, looking the videos, I have noticed that too much zoom: little repaid error whit good resolution :)

do you have idea for to insert the videos in this forum?

Very interesting.

I think this is the highest speed for tuft testing that I've seen.

The article(s) on this subject at were conducted at much lower speeds... 70-80 km/h.

Just watched the videos... awesome :)

If you do this again, try only cracking the windows too... I found similar distrubrances with my windows barely open compared to fully opened...
