Abstract
A simple device consisting of a waveguide and two loudspeakers is proposed for generation of low-frequency standing acoustic field with high amplitude of acoustic velocity and particle displacement, which is primarily intended to be used for stabilization of electric discharges in acoustic field. A coupled model of loudspeakers and nonlinear wave equation including waveguide radius variability, thermoviscous attenuation in boundary layer and minor losses is developed. The results of the conducted experiments validate the model revealing that the minor losses and acoustically generated turbulence in the boundary layer represent an important means of acoustic energy dissipation in this and similar applications.
