Bleaching of a polydisperse aqueous aerosol by laser radiation

The bleaching of a polydisperse aqueous aerosol by cw 10.6 μ wavelength laser radiation and diffusive evaporation of the water droplets were investigated using a numerical solution to a set of equations. The spatial and temporal dependences and the parameters characterizing the bleaching process were found. The parameters of the bleaching process were analyzed as a function of the radiation energy flux density, initial temperature of the droplets, evaporation coefficient and optical constants of water, and initial aerosol dropletsize distribution function. The efficiency of the bleaching process was investigated and the results compared with experiment.
