ABSTRACT:
To evaluate the droplet evaporation and liquid/vapor phase interactions in aerosols and sprays, an optical method for measuring the concentration of the gas phase is provided. Two laser beams are passed through a mixture of the gas and liquid particles, one beam having a wavelength not absorbed by the gas and the second having a wavelength which is absorbed by the gas. Attenuation of each beam is measured, the droplet size distribution is measured by a light scattering technique and the concentration of gas in the path of the light beams is determined from the attenuation of each beam, the droplet size distributions, and known parameters.
