Interaction of a free shear layer with a synthetic jet
Matějka, M. ; Uruba, Václav
The reasults of experimental study of a free shear layer and a synthetic jet interaction are presented. The PIV method has been applied.
Příspěvek k výzkumu receptivity volné smykové vrstvy při jejím buzení syntetizovaným paprskem
Uruba, Václav ; Matějka, M.
Receptivity properties of a free shear layer have been studied experimentally. Excitation has been performed using synthetic jet parallel or perpendicular to the shear layer issuing near the shear layer origin. Substantial significance of both excitation frequency and synthetic jet orientation has been shown.
Effect of the power change on time averaged characteristics of the steam flow downstream the LP stage of the 210 MW turbine
Jonáš, Pavel ; Mazur, Oton ; Uruba, Václav
Preliminary results of hot-wire anemometer measurements are presented that were performed in wet steam flow downstream the LP stage of the turbine TG21 in Prunéřov II at the power 210 MW and 140 MW.
Fázově středované charakteristiky proudění mokré páry po proudu za NT stupněm parní turbíny
Jonáš, Pavel ; Mazur, Oton ; Uruba, Václav
Single rotary inclined hot-wire anemometer was used during the investigation of the phase averaged characteristics of unsteady wet steam flow inside the LP stage of the steam turbine TG21 at the power station Prunéřov II. The effect of the passage from the nominal regime to the reduced one on the flow structure is outlined.
Řízení proudění pomocí syntetizovaných paprsků
Uruba, Václav
Generation, evolution and interaction of synthetic jets are reviewed.
Použití anemometru se žhaveným drátkem při modelování šíření škodlivin v aerodynamickém tunelu
Moryń-Kucharczyk, E. ; Jonáš, Pavel ; Mazur, Oton ; Uruba, Václav
Measurement of molar concentration in CO2 jet issuing from a narrow pipe into an air stream is described. Two methods of concentration measurement have been compared - using the analyser Guardian and using a special hot-sensors probe.
Výskyt velkých kapiček v okolí posledního stupně parní turbíny 210 MW
Uruba, Václav ; Jonáš, Pavel ; Mazur, Oton ; Řehák, Vratislav
The method of detection of big water droplets in the wet steam flow based on hot-wire anemometry is used for analysis of the flow behind the last stage of the 210 MW steam turbine in two operational regimes.
Předběžné výsledky o charakteristikách proudění mokré páry za NT stupněm 210 MW turbíny
Jonáš, Pavel ; Mazur, Oton ; Řehák, Vratislav ; Uruba, Václav
Results of the unsteady wet steam flow structure investigation are presented. Measurement was executed by means of a single rotary inclined hot-wire anemometer.
Návrh generátoru syntetizovaného paprsku
Uruba, Václav
A coupled fluid-structural model of a synthetic jet actuator is introduced. Sensitivity analysis to various actuator design parameters is presented.
