well look at windtunnel tests, mostly every plane, car, truch, train, boat, building, etc that they put in
there is a much scaled down version of whatever there testing. even today with computer sims
they still use the windtunnel. there not to concerned about air molicule sizes, and it produces
accurate results.
Me thinks ye should looketh more into the magic of the tunnel. Someone previous mentioned Reynolds number, that
IS the factoring in of the differences in air molecule size and scale behavior. That is why
THEY'RE accurate.
I'm no areonuatical engineer though.. I just play one on the internet
And not a very good one at that.
