Acoustic agglomeration of sub-micron particles
The treatment of aerosols with high intensity sound waves induces efficient particle agglomeration in the 0.5 - 5 micron range. This paper presents and discusses the first results of an investigation into the effectiveness of acoustic agglomeration in the sub-micron range. The measurements were performed with a 21 kHz sound source located in a cylindrical experimental chamber designed to reduce the amplitude of acoustic standing waves. The aerosol was produced by the evaporation and condensation of a glycol based liquid. The evolution of the total particle concentration and mass of the aerosol in the 0.02 - 5 micron range, with and without acoustic treatment, is shown. Results have demonstrated that the effect of acoustic treatment on these sub-micron particles is higher than was expected. The technique is being developed as a gas cleaning process.
