Original Abstract

Many industrial devices positively utilize the action of centrifugal forces induced by highly swirling flows (e.g. hydrocyclones, swirl burners). On the other hand swirling flow causes significant problems in operation of turbines or aircraft. Presented paper is going to review the current state of knowledge about swirling flows (stability of swirling flows, vortex breakdown phenomenon, helical precessing vortex core) and outline possible approaches leading to better understanding of these phenomena. Inevitably it is a mixture of analytical techniques, computational simulations and advanced experiments. It also proves efficient to employ some of the methods for spatio-temporal description of dynamical systems like proper orthogonal decomposition (POD).
