MODELING OF THE FINE PARTICLES DRIFT IN ACOUSTIC RESONATOR USING CFD–PACKAGE

Abstract

The particles driftin closed tuberesonator by the influence of viscous drag force using CFD package was considered. On the left bound of resonator gas velocity oscillates harmonically at the first resonant frequency. The four vortices of Schlichting in boundary layer and four vortices of Rayleigh were shown. The particles by the influence of its own drift and acoustic flow accumulate on the ends of the tube. Maximum particle drift near the boundary between vortices was observed. Comparison of the results with other author results shows satisfactory accuracy.
