Vortex Cores and Vortex Breakdown

Abstract

A number of fundamental discoveries were made concerning vortex cores and vortex breakdown. Bifurcation processes of a mathematical nature are fundamental in understanding the two kinds of vortex breakdown -- of bubble type and of spiral type. Additional mathematical procedure were used for the calculus of variations, to analysis axisymmetric vortex motion with swirl and helical vortex motion. The work on helical motion is described, and the work on axisymmetric vortices with swirl is given in preliminary form. (jhd)
