Regarding scoops laminar flow and slipstreams etc

I have to say form the limited experience I have had this summer building
and testing a research flume (sort of like a air tunnel but using water
instead of air), fluid dynamics is (for those of us limited in math and with
no access to  super computers) very much an empirical practice.

While you can look at a model/set up and make some predictions as how the
fluid will flow around/through it, often it will be very surprising to see
the flow in reality.

Time restraints will probably preclude this but I want to build my Revell
Vanagon model and stick it in the flume to watch the flow around it!

Years ago the list was discussing flow around the van etc, all kinds of
crazy and neat ideas surfaced. I had the idea of sticking little yarn
"tell-tales" (tell-tails?) all over the van then driving at various speeds
in still air and see (via chase van) just how the air flowed over the
shoebox.
