roulishollandais it's not really that there's 'no solution'
per se, it's just that there's no closed solution to the NS formulations...a complete examination of the equations of motion and thermodynamics, with repect to fluids yields two very important non-dimensional quantities...Mach Number and Reynold's number--- that is exactly where ALL of our problems arise...
Aerodynamics, is for the most part an experimental art, and it is an art, as so many technical field's really are...
Mad(flt)Scientist has a habit of revealing some of the secrets of design on pprune...for serious students of the field I believe his posts are definitely worth a read...
of course we must all remember two very important thing to progress with a design... for better or worse, new ideas are
always dangerous and that nature laugh at complex mathematics...laughs!!!
