Abstract
A recent theory of the nearly axisymmetric vortex breakdown in a pipe is
presented. We study the motion of an axisymmetric and inviscid swirling
flow in a pipe with certain boundary conditions that may reflect the
physical situation. The theory is built of global analysis of solutions of
the Squire-Long equation and linear stability analysis of these solutions.
The theory unifies the major previous theoretical approaches and provides
for the first time a consistent explanation of the physical mechanism
leading to the vortex breakdown phenomenon as well as the conditions for
its occurrence.
