Aerosol Propagation Effects

Abstract

A model has been developed for the prediction of the time dependent properties of the gas surrounding a water droplet under irradiation by a high intensity laser beam. The basic phenomena included in the model are absorption, heating and vaporization in the droplet and convection, thermal conduction and diffusion in the gas. The model assumes volume absorption by the droplet, a constant pressure gas, and that the initial vapor velocity is much less than the local sound speed. The conditions under which these assumptions are appropriate have been identified. A number of preliminary calculations are presented.
