Template:Short description The Kaufmann vortex, also known as the Scully model, is a mathematical model for a vortex taking account of viscosity.[1] It uses an algebraic velocity profile.[2] This vortex is not a solution of the Navier–Stokes equations.Script error: No such module "Unsubst".
Kaufmann and Scully's model for the velocity in the Θ direction is:
The model was suggested by W. Kaufmann in 1962,[3] and later by Scully and Sullivan in 1972 at the Massachusetts Institute of Technology.[4]
