Rankine vortex

A two-dimensional circular flow in which an inner circular region about the origin is in solid rotation:
ams2001glos-Re17
where V is the tangential speed and r the distance from the origin.

The outer region is free of vorticity, the speed being inversely proportional to the distance from the origin (as in the ''V''–''R'' vortex),
ams2001glos-Re18
This vortex has occasionally been used as a model for the wind distribution in a hurricane.
