Abstract: [eng] [cze]
In this contribution, the unsteady behaviour of a jet, impinging into a trough cavity is described. The mechanism of the switching of the jet is clarified and the effect of the impingement angle is discussed. The problem was studied both experimentally and numerically. The numerical investigation is performed using a commercial package Fluent 6.1, while the experimental data are obtained using the hot- wire probe. The experimental and the numerical data are compared and discussed. V této práci je popsáno nestacionární chování paprsku proudu, dopadajícího do korýtkové kavity. Je popsán mechanismus vzniku oscilací a je diskutován vliv impaktního úhlu. Pro výzkum bylo využito jak experimentálních, tak numerických metod. Pro numerické výpočty byl použit komerční solver Fluent 6.1, experimenty byly provedeny sondou se žhaveným drátkem. Experimentální a numerická data jsou porovnána a diskutována.
