Vortex Motion


Flows at high Reynolds numbers develop islands of concentrated vorticity, concisely called vortices, embedded in a low-vorticity or virtually irrotational ambient fluid. The velocity field can be decomposed into two constituents: an irrotational component prevailing in the absence of the vortices, and a rotational component associated with the localized vorticity distribution. The latter can be conveniently expressed as an integral over the volume of fluid occupied by the vortices. At high Reynolds numbers, viscous forces are insignificant away from flow boundaries and the vortices evolve according to simplified rules dictated by the vorticity transport equation.
