Computational grids usually tend to be solver-specific, so you'll
probably have to generate your own. As for experimental data, though,
the ERCOFTAC database has a large number of relevent flows. The web
address is: http://fluindigo.mech.surrey.ac.uk/
"ERCOFTAC" stands for European Research Community On Flow
Turbulence And Combustion. Access to the database is by
account only, but completing a simple form gets you registered.
Data from 77 test cases are presented in tabular form. These
are typically fundamental fluids test cases (flat plates, jets,
etc.) but a few more applied data sets appear as well. Most
are experimental but a few LES and DNS studies are in there also.
Good Luck,
Paul

Steve,
I don't know if this will help but our company manufactures high speed
film (up to 10,000 pictures per second) and digital (up to 3000
pictures per second) image recording products. If you stop by the web
site listed below you will get a good understanding of what high speed
imaging is all about. I trust that the information at our site will help
you with your translation task.
In addition to the many sample images (fluid flow related) at the site,
there is also a demonstration copy of our Windows based high speed motion
acquisition and analysis software available for download. This software
has a sample high speed movie included and you're welcome to take a copy
if you like.
If you have any further questions about high speed imaging after visiting
the site please send me an email, I'll be glad to help. Good luck with
your project.

This all seems pretty inconsequential to me. One who drafts using CAD
is a Draftsman (or person), one who designs using CAD is a desinger,
and an engineer who uses CAD is still an engineer.
This discussion reminds me of one in medicine severa years ago.
Surgeons that used a microscope during surgery wanted to be
"microsurgeons" until someone asked how short you had to be in order
to be a "microsurgeon"!
