Chaz, I don't know. Who
really does? The vast majority of wind tunnel smoke trails held up as proof show only the flow down the vertical plane of symmetry. A 2D slice through the center of a 3D field tells us nothing about the rest of the field. That leaves intuition, speculation and good old fashioned opinions. (shrug) Even with PIV and CFD how to convey the complex data is still hard stuff. Tuft testing seems like one of the most pragmatic tools. Gee, what if some grad student made his/her paper just about one classic aero problem (say, a 2002 4WD Tundra xCab - wink) but using all the tools and comparing the results for similarities and differences. Wouldn't that be cool?
Cheers
