Use of radial synthetic jets for active control of annular jets
Broučková, Zuzana ; Šafařík, Pavel ; Trávníček, Zdeněk
This experimental study deals with an annular jet, which is actively controlled by means of the radial synthetic jet. Measurements were performed in air by means of the Pitot tube.Visualization was also performed. A possibility of flow control of the means annular jet was proved. A suitable frequency of control synthetic jet was 600 Hz.
Calibration of Five- Hole Conical Probe for High-Speed Flow Measurements
Kožíšek, Martin ; Šafařík, Pavel ; Luxa, Martin ; Šimurda, David
This report deals with calibration of a conial five-hole probe in the region of transonic velocities. The probe is designated for research on threedimensional flow pattern. The method of flow angle calibration, data asquisition and evalution of data are described. Data evalution is desribed to samples on higher subsonic velocities.
