Orthokinetic agglomeration in an intense acoustic field

Experimental investigations of acoustic agglomeration were performed with sound pressure levels ranging from 145 to 155 db (re 20 μPa) and frequencies from 600 to 3000 Hz under traveling-wave conditions. The temporal variations of mass distribution were measured with Berner's impactors. The mass distribution function of the agglomerated aerosols was found to be bimodal and agree with the orthokinetic acoustic agglomeration theory. The numerical simulation of the agglomeration was conducted using sound pressure level, frequency, particle size, and mass loading as the parameters. The discrepancy in the comparison between the theoretical and experimental results was reduced by modifying the refilling factor.
