Flash Liquid Aerosol Production Method and Apparatus

Abstract: 

Method and apparatus are presented for producing liquid aerosol particles of narrow size distribution by dispersing one or more droplet columns and impinging these droplets onto a vibrating cavitation surface to create a high density fountain of aerosol particles. Flash cavitation of these impinging droplets is achieved through controlled disruption on impact of the impinging liquid droplets with a vibrating surface wherein the measured size and frequency of droplets promote complete disruption of the droplets into aerosol particles with substantially no splash disruption or agglomeration thus efficiently producing small liquid aerosol particles having a narrow size dispersion range.
