A few weeks ago I had coffee with a talented Aerodynamist which after years of working with the big automobile manufacturers started to explore some other options, including doing some work independently.
I had an opportunity to see some of his work on the laptop he brought, and he explained how to read and interpret some of the CFD images, what the colors meant and what to look for.
No college credits accumulated, but I felt I was tutored by an expert, especially once he looked at a from scratch design I've been working on and provided helpful commentary.
What brought us together was my Chevy S-10's aerodynamic modifications which are posted here in this forum and on other places across the Internet. We happen to live in the same town so a coffee get together ensued.
In order to quench some of my curiosity regarding how the truck works CFD wise and what that roof wing really does he worked up some studies for me, which I will do my best to share including some of the e-mail comments I managed to add to the images below.

1. Truck was raised by previous owner by about 2-inches (
change made).
2. Roof wing shape is close enough for general discussion purposes.
3. Chin spoiler and rear spoiler look to be accurate and to scale.
4. The Sportside/Sidestep bed verses Fleetside bed is not addressed as it was not a concern at the time.
5. Tonneau cover on bed is included on the images.
I know these might be hard to read, so you can go to my Photobucket account and do a Ctrl+ command to zoom in and read some of the text.

Oh yea, if you want to explore some more images, non-related to this quick/rough study feel free to click on the link below. Not a whole lot there right now, but I assume there will be one day.
