Abstract: Authors measured instantaneous velocities in points along the axis of a synthetic jet and evaluated there the spectral density of the measured values. Analysis of these spectra necessitates knowledge of quantities - such as the dissipation rated of eddies – difficult to evaluate and usually not know. In the present case they were found from to the earlier performed fit to quasi-similarity solution of the flowfield, based upon the one-equation model of turbulence.
