Vortex ring
Zaremba, Matouš ; Šperka, Oldřich (referee) ; Rudolf, Pavel (advisor)
The aim is to design equipment for the production of a vortex ring. The work deals with design of equipment, manufacturing and experimental verification of the functionality of some experiments with vortex rings. The work also includes a theoretical part which mathematically describes the motion of the vortex ring.

Trapped Vortex Ring
Tesař, Václav
Paper discusses an almost unknown and yet interesting operating principle of fluidic nomoving-part devices for flow control. The principle is based on the properties of vortex rings. A standing vortex ring is kept in a semi-toroidal recession positioned opposite to an annular nozzle from whichissues an annular fluid jet. The ring can exist in the recession with two alternative senses of rotation so that the annular jet is led to either the central exit through the centre of the vortex, or to the outer spacepast the outer vortex circumference.
