Vortex generators trials and choice (post 3 of 5)

3rd Position, 2nd geometry along the roof end

2nd geometry location proposed by

Dheeraj Sagar et Al, 2010, Aerodynamic Effects of Rear Spoiler and Vortex Generators on Passenger Cars, Proceedings of ICTACEM 2010 , International Conference on Theoretical, Applied, Computational and Experimental Mechanics, December 27-29, 2010, IIT Kharagpur, India

This geometry was adopted for remaining trials.

Some improvement in the tufts movements along the window side edges. The tufts on the window center and bottom still move some.

See many mods in detail with results on my modification thread for my 1999 Acura EL, similar to US Civic EX

Facts, please, give me the facts! Theoretical knowledge is verified by empirical knowledge! Check Einstein's General Relativity Theory E=MC^2! Every few years some new astrophysics observation and data prove some of Einstein's theory predictions more than a century old.
