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]
