Dynamika syntetizovaného paprsku
Uruba, Václav ; Knob, Martin ; Popelka, Lukáš
The paper presents recent results obtained in synthetic jet research in IT, Fluid Dynamics Department. The case in quiescent air is examined experimentally using time-resolved PIV method. Results concerning a synthetic jet mean characteristics and dynamics behaviour are presented.

Nestacionární charakteristiky impaktního proudění do korýtkové kavity
Knob, Martin ; Antoš, Pavel ; Adamec, J.
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.

Comparison of experimental and numerical data in 2D impact flow
Knob, Martin ; Antoš, Pavel ; Adamec, J.
In the contribution, the experimentally obtained and the numerically computed data in a two- dimensional impinging jet flow are compared. The calculations were performed using a commercial solver Fluent v. 6.1, while the experimental data were obtained using a hot- wire probe. In the calculations, both the k-SST and the RSM models of turbulence were employed. The comparison has been done for three various jet hydraulic diamater and jet mean velocity based Reynolds numbers, 2800, 8400 and 1400, respectively.
