	Nestacionární charakteristiky rovinného paprsku, vstřikovaného do korátkové kavity Knob, Martin ; Uruba, Václav ; Antoš, Pavel ; Popelka, Lukáš ; Šafařík, Pavel ; Adamec, J. In the article, the results of the biorthogonal decomposition of a 2D TR PIV data of a jet impinging into a trough cavity, are presented. The obtained spatiotemporal structure is shown and its physical meaning is clearly explained. Detailed record
	Nestacionární vírová struktura vyvolaná parpskem tekutiny vstřikovaným do korýtkové kavity Knob, Martin ; Uruba, Václav In the contribution, the results of vortex identification in an unsteady TR PIV data of a cavity subject to a jet impingement are presented. The main phenomena, such as vortex loop are shown and their relation with local pressure minima is described. Detailed record
	Nestacionární chování rovinného paprsku, injektovaného do korýtkové kavity Knob, Martin ; Šafařík, P. ; Adamec, J. The unsteady behavior of a plane jet impining into a trough- like shaped cavity is studied in the range of jet hydraulic diamater based Reynolds numbers between 3000 and 20000, the cavity aspect ratios between 1:2 and 3:4 and, finally, for the impingement angles between 0 and 15°. It is explained in detail, that the jet- swinging is caused by the unsteady Coanda effect. Detailed record
	Experimentální a numerické vyšetřování nestacionárního chování impaktního proudu do korýtkové kavity Knob, Martin ; Antoš, Pavel ; Adamec, J. In this contribution, the unsteady behaviour of a jet impinging into a trough- like shaped cavity is discussed; the investigation is performed both experimentally and numerically. The unsteady character of this flow is considered a result of instability in otherwise symmetrical flow- field. The mechanism of the jet swinging is then identified as an action of the Coanda effect between a jet and a quasi- wall- jet. Detailed record
