Hi ft...
"It applies to a steady flow of an incompressible, inviscid fluid."
I think that is the point I attempted to make, inelegantly.
The authors of the paper in question make an elegant case for a new way to teach "Introduction to Lift". The math and the relationships among the variables are clear, and persuasive.
The "sacred" maths and several independent theorems are available on Wikipedia, I checked. I have never understood the apparent need to make lift complex, and pay homage to a Swiss hydrologist.
Any new approach will make "waves" and a vortex or three. Toes will be compressed in its forthcoming popularity...
As to the lack of facts in this post, I will incorporate the paper here, by reference.
