Resumo
The dynamics of aerosol particles and acoustic streaming of a polytropic gas in a closed resonator at the first resonant frequency are investigated numerically. The spatial differential operators in governing equations are factorized in axial and radial directions. The occurrence of two Schlichting and two Rayleigh toroidal vortices are revealed. The impact of acoustic streaming on distribution of aerosol particles is investigated. It is shown that eigen drift and acoustic streaming move particles to the ends of the resonator forming there zones with increased particles concentration. The comparison of particles distribution shows a satisfactory agreement with results computed using OpenFOAM package.
