The Advantage of Aerosol Manipulation by Twin Types of Acoustic Resonances

Zhenghui Qiao, Yaji Huang, Vincenzo Naso, and Wei Dong
Abstract—In order to make full use of the potential advantage of the multiple type of acoustic resonance, twin types of acoustic resonances (TTAR) are proposed to construct acoustic resonant device for manipulating aerosols with low energy consumption for acoustic source. The TTAR is realized by the frequency coupling between the Helmholtz resonator and the harmonic waveguide. The TTAR consists of the 1st type of resonance based on the Helmholtz resonator and the 2nd type of resonance based on the harmonic waveguide. The sound pressure generated at resonance frequency 1268Hz caused by the 1st type of resonance is amplified 1.8 times comparing to that caused by the acoustic source without the 1st type of resonance. The peak sound pressure caused by TTAR is amplified 1.1 times than that caused by the single type of acoustic resonance based on the harmonic waveguide. The variation of sound pressure distribution for the TTAR and the STAR has the same regulation; however, the former peak sound pressure is much larger than the later at the same energy consumption for acoustic source. Especially, benefit from this advantage, the aerosols and the air medium in waveguide are separated by TTAR in the finite space within waveguide.
