Re your 2d vs 3d flow discussion, thats kind of what I figured. But let me try & pose the question a different way. Assume the pgm is a good airfoil simulator. It allows entry of any airfoil shape expressed in 2d. So I input the x,y values of airfoil A & B, it calculates the polars & coefficients at assumed fluid & velocity parameters. I dont know actual lift & drag of the 'wing' until the 3d info (span, planform geometry etc) is defined, but, if the wings will be identical in that regard, doesnt the 2d results allow me to qualitatively compare airfoil shapes A & B?

So now if I input the coordinates for 2 'airfoils' which just so happen to look like a fuse side view & again assume the span (fuse width) is the same in both cases, isnt there some information to be learned?
