Spectral analysis of a synthetic jet
Original language description
In their earlier publications, the present authors discovered a phenomenon, previously not reported, of sudden substantial change in the character and structure of axisymmetric synthetic jets that occurs at relative axial distance 50 nozzle diameters. Itwas suggested the change is associated with the transition from the regime dominated by coherent vortical structures into the flow dominated by stochastic turbulence. To validate this hypothesis, frequency spectra were incestigated at various locationsin a synthetic jet generated in d = 4mm dia. nozzle at the forcing frequency ff = 30Hz. The results corroborate the idea. In addition, the analysis has lead to several previously not known facts about structure and character of synthetic jets.
