Abstract
The role of coherent structures in jets and mixing layers becomes deciding between aerodynamic and acoustical characteristics of jet flows. This is true for amplification of acoustical feedback in realization of different kinds of resonance. The simplest of such cases is the case of jet issue from a receiver (Fig. 5.1, a) that is a resonator with resonance frequencies belonging to the range of the jet sensitivity to periodical excitation. Here the jet is excited without any outer sound sources [5.1].
