Abstract
Abstract
The agglomeration by acoustic waves is a phenomenon in which the vibration of fine particles is induced by irradiating the fine particles suspended in the atmosphere with ultrasonic waves, and the collided particles adhere to each other by causing frequent collisions between the fine particles, thereby increasing the particle size. Ultrasonic agglomeration of an aerosol flowing in a circular tube by using a conventional method with a sound field with a different diameter from the duct causes pressure loss. In this study, a cylindrical aerial ultrasonic source with the same diameter as the circular tube was used, and the aerosol was agglomerated without pressure loss. Several types of agglomeration chamber for the aerial ultrasonic source were fabricated, and the effect of the input power of the source on the agglomeration was measured.
