Mathematical model for a vortex that takes viscosity into account
The Kaufmann vortex, also known as the Scully model, is a mathematical model for a vortex taking account of viscosity. It uses an algebraic velocity profile. This vortex is not a solution of the Navier–Stokes equations.
Kaufmann and Scully's model for the velocity in the Θ direction is:
formula_1
The model was suggested by W. Kaufmann in 1962, and later by Scully and Sullivan in 1972 at the Massachusetts Institute of Technology.
