Description	Práce se věnuje problematice Synthetic Jets a přináčí výsledky termoanemometrických experimentů a vizualizace metodou kouřového drátku (cs) An air round jet was generated by means of a zero-net-mass-flux actuator. Generation (synthesis) of the jet flow was tested experimentally by smoke visualization and hot-wire anemometry, and a satisfactory function was confirmed. The choice of suitable oerating frequency was found by means of theoretical as well as experimental approach: the resultant 75 Hz was found near the theoretically derived resonance frequency as well as near the maximum measured time-mean velocity. The hot-wire data were decompoed using the phase-averaged technique. The experiments present a formation of the synthetic jet when fluid puffs travel downstream and the periodic component of the velocity gradually diminishes. The investigated, originally pulsatile jet resembles a conentional jet for the axial distance greater than 20 diameters from the orifice, where the streamwise decay of the centerline time-mean velocity is described by the proportionality with the exponent An air round jet was generated by means of a zero-net-mass-flux actuator.
