Acoustic Control of Turbulent Jets (Foundations of by A.S. Ginevsky,Y.V. Vlasov,R.K. Karavosov

By A.S. Ginevsky,Y.V. Vlasov,R.K. Karavosov

Results of experimental learn on aerodynamic and acoustic regulate of subsonic turbulent jets by way of acoustic excitation are provided. It was once verified that those keep watch over tools, originated by means of authors, not just can accentuate blending (by acoustic irradiation at low frequency), but in addition particularly ease it (at high-frequency irradiation). This learn monograph offers the up-to-date result of the authors supplemented through different investigations carried out in united states, Germany and nice Britain. The equipment for the numerical simulation of subsonic turbulent jets lower than acoustic excitation are defined intimately, and examples are reviewed of useful functions, together with aid of turbojet engine noise and acoustic keep watch over of self-sustained oscillations in wind tunnels.
