Abstract
The features of developing a counterflow zone (bubble-mode vortex breakdown or vortex explosion) at the center
of an intensively swirled flow produced in a liquid-filled cylindrical container with a rotating endwall have been
studied. The observation showed that the scenario of developing a bubble-mode breakdown zone with generation
of counterflow is the same for cylinders with low or high aspect ratio, and it remains independent of stationary-nonstationary
transition boundary for the main vortex flow.
