Abstract:

Results of observation of generation of aerosol particles and drops in mixtures of saturated water vapor with air and molecular gases are described in the paper. The kinetics of the aerosol and drop generation was studied in the absence and under impact of monokinetic beam of electrons on the gas mixture with supersaturated water vapor, formed in the process of the controllable pressure unloading of the prepared gas mixture from a spherical chamber of 1.4 m in diameter to vacuum reservoir of 40 m³ in volume. The kinetics of generation of aerosol particles and drops was recorded by the method of laser beam (drop) small-angle scattering and with the help of aerosol spectrometer (particle). Experimental results show significant dependence of generation of drops and particles on the impact of ionizing radiation.
Three-dimensional computer simulation of the process of supersaturated water vapor condensation on ions by methods of Boltzmann lattice equations (LBE) and molecular dynamics (MD) describes qualitatively the obtained experimental results.
