The attenuation of sound energy in soot and fog aerosols
Over the last few years, the limitations of conventional filtration technology for separation of particles with diameters less than 5 microns has become increasingly evident. One method which could enhance the efficiency of such devices in this size range is acoustic agglomeration. The realisation of the industrial application of this process requires the design of an efficient agglomeration chamber. The dimensions of such a chamber will be determined by both the choice of sound frequency and the attenuation of the sound energy by the aerosol. This paper compares measurements of the acoustic amplitude attenuation coefficient for liquid (fog) and solid (soot) aerosols with theoretical values.
