Kaufmann (Scully) vortex

The Kaufmann vortex, also known as the Scully model,^[1] is a mathematical model for a vortex taking account of viscosity. It uses an algebraic velocity profile.^[2]

Kaufmann and Scully's model for the velocity in the Θ direction is:

V_{\Theta }\ (r)={\frac {\Gamma }{2\pi }}{\frac {r}{r_{c}^{2}+r^{2}}}

The model was suggested by Scully and Sullivan in 1972 at Massachusetts Institute of Technology, and earlier by W. Kaufmann in 1962.^[3]
