Abstract
The accidental releases of toxic or flammable gases often form a two-phase mixture, consisting of vapour and liquid droplets of the released species, and entrained humid air. A substantial fraction of the pollutant substance may be initially in the form of airborne liquid droplets. The aerosol phenomena may therefore have a substantial influence on the temperature and density evolution of the source term, and on the subsequent heavy gas dispersion. In particular, the deposition of substance liquid droplets may cause a substantial decrease in concentration.
