摘要：
Dynamics of the distribution of aerosol particles in acoustic field inside a hyperbolic plane resonator is numerically studied. The exact value of the first resonant frequency, as well as the amplification of gas velocity amplitude are found. The existence of acoustic flow in the form of four Rayleigh and four Schlichting vortices is revealed at first resonant frequency. Dynamics of the initially uniformly distributed particles and their drift at the first resonant frequency is simulated. Five zones of attraction of aerosol particles (acoustic traps) are observed. The influence of entrainment coefficient of particles on their distribution is analyzed. (C) 2018 Elsevier Inc. All rights reserved.
