Measurements of the initial acoustic agglomeration rate averaged over the volume of the measurement chamber, as a function of the applied acoustic power, and of the initial aerosol particle concentration, have been made at 10 and 21 kHz. The results show that at both frequencies the acoustic agglomeration rate is directly proportional to the square of the wave velocity amplitude. A model that takes account of sound attenuation in progressive or standing wave situations has been devised. It is shown that an enhanced agglomeration can be achieved under standing wave conditions. The model also yields a number of non-dimensional parameters which permit comparison of measurements made in chambers with different geometry.
