Results of experimental examine on aerodynamic and acoustic keep watch over of subsonic turbulent jets via acoustic excitation are awarded. It used to be established that those keep watch over tools, originated by means of authors, not just can accentuate blending (by acoustic irradiation at low frequency), but additionally particularly ease it (at high-frequency irradiation). This study monograph offers the up to date result of the authors supplemented by means of different investigations performed in united states, Germany and nice Britain. The tools for the numerical simulation of subsonic turbulent jets less than acoustic excitation are defined intimately, and examples are reviewed of useful functions, together with aid of turbojet engine noise and acoustic regulate of self-sustained oscillations in wind tunnels.
