Abstract

Temporally and spatially resolved measurements of the number density of water droplets in an intermittent aerosol were experimentally demonstrated by a laser-induced breakdown technique. The temporal number density distribution is clearly explained by temporal variations in the air pressure at the nozzle caused by an electric valve, the number density of droplets in the steady-state aerosol as a function of air pressure applied to the nozzle, and the steady-state air flow speed as a function of the air pressure applied to the nozzle. The spatial resolutions in the radial and axial directions are also discussed; they were determined from the breakdown threshold intensities of water droplets and air.
