Tuft testing! 1998 Ford Escort ZX2 (front hood, windshield and rear glass and lid)

I have said I was going to do this for a long time. Life seems to always get in the way of scientific studies when you are a layman scientist However, I made today it!

Photos of the areas tested:





The reason for the fewer number of tufts on the front is because I ran low on time. My brother was the camera man, and he had homework to do. I had to make do with what I had. It told me all the info that I needed to know though I added the windshield wiper cover today in an effort to reduce rear turbulence, hence it was not painted. Whether it helped or not in unknown, as I did not perform ABA testing.

Here is the video:


Excuse my brother and I. We tend to act goofy when we get together, research or not

I have another video that will be uploaded tomorrow that shows the rear lid better, and has a panned out shot of the entire rear glass.

What I infer:From what I can tell, there is attached flow on the hood and the windshield. I was concerned that there was turbulence there. On the back, it is a mess! It is all turbulent, except for maybe the tufts on the top of the rear glass and around the brake light. *There is semi-attached flow and a vortex there, respectively*.

*Of course, I am no aero expert. So I await the aero gurus to dissect the results of this test so we really know what is going on
