Abstract

An acoustic aerosol removal system with the addition of water droplets was examined in this paper. Previous studies used a radiating plate, attached to an ultrasonic transducer, to create stationary waves in an air duct. The acoustic effects were found to aid the aerosol deposition process. In this study, the radiating plate was subject to an inflow of water, which was vibrated and micron size water droplets were generated. It was found that these extra micro size droplet lowered submicron incense smoke particle concentration by 34%. The micron size agglomerates formed with liquid droplets with aerosols were found to be easily deposited. This process has the potential to disinfect airborne bacteria or viruses with selected antimicrobial agent as the aerosolized liquid droplets.
