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). 000008745 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000008745 653__ $$aSwirling flow, Stability, Vortex rope, Proper orthogonal decomposition. 000008745 7112_ $$aEngineering Mechanics 2014$$cSvratka (CZ)$$d12/05/2014 - 15/05/2014$$gEM2014 000008745 720__ $$aRudolf, P.$$iŠtefan, D.$$iPochylý, F. 000008745 8560_ $$ffischerc@itam.cas.cz 000008745 8564_ $$s535053$$uhttps://invenio.itam.cas.cz/record/8745/files/181-Rudolf-CD.pdf$$yOriginal version of the author's contribution as presented on CD, keynote, paper No. 181. 000008745 962__ $$r70 000008745 980__ $$aPAPER
