If I could perhaps add into the 'lid-driven cavity' debate - are there any practical experiments that have been performed that could assist clarification of the many numeric experiments?

Ghia's paper is just well written and goes to a high Reynolds Number. I really dont know of any actual experiments though. I still think Gupta's paper is worth looking into, and it is relatively short compared to Ghia's. Also, there is a dissertation online by Debbie Sastrapradja titled, Rayleigh Streaming Simulation Using the Vorticity Transport Equation, that does a good job going through the equations and derivation of the boundary conditions for the streamfunction-vorticity model. It used to be online anyway.

you will have to do a search for it. I can't remember where I found it, but I was able to download it from the web. She went to Penn State
