Abstract : Small particles (near 1 micron) suspended in a gas are difficult to remove by conventional separation equipment. A promising technique is to expose the suspension to a field of high-intensity standing sound waves in which the motion or particles relative to one another leads to collisions and agglomeration. The results increase in the average particle size then facilitates particle removal by conventional means. Experiments indicate marked increase in the agglomeration rate if the intensity of the oscillations becomes so high that the sound waves steepen to form oscillating shock waves. Particles also exhibit a strong tendency to drift to the nearest velocity node.
