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