摘要：
Experimental investigation of an open test section wind tunnel's free jet velocity pulsation was carried out by means of CTA. Both discrete narrow band and wide band vibrations centered by Strouhal number St=0,48 were observed. Some aeroacoustic mechanics were considered for narrow band harmonics explanation.
