    Centrifugal Vacuum: Is Mach 1.0 the Limit?

    Strive states it well. Notice that he does NOT use Bernoulli's ... "Higher velocity over a surface equals lower pressure on that same surface". I believe his approach is right... But what do I know, I've been working this thing for over 25 years and still haven't got it off the ground. Help! :)

    Centrifugal Vacuum: Is Mach 1.0 the Limit?

    --- Blainiac, Very nice! In your equation, is rho the density of air? Theta is the angle the fins make with the base (or inner diameter of fin connection point), yes? Wait, I see... You're using Bernoulli Navier-Stokes -- That is, you're assuming that the pressure will decrease based upon...

    Interesting discussion! Any progress since September 2014, blainiac? :)
