Separation in Slightly Viscous Flow

The New Theory of Flight presented on The Secret of Flight offers a new analysis of the central problem of separation in slightly viscous flow modeled by the Navier-Stokes equations with a slip boundary condition. This analysis is fundamentally different from the classical analysis by Prandtl of boundary layer separation with a no-slip boundary condition, which has dominated modern fluid mechanics.

Separation with slip show to take one of the following forms illustrated in the oil film visualizations above:
  1. Rotational separation with opposing flows (top)
  2. Parellel flow separation (bottom)
The analysis is presented in the upcoming book The Secret of Flight in Chapters 24 - 30. Why not take a look!
