Effect of Ultraviolet Radiation on Evaporation of Suspended Alcohol Droplets
The influence of 390-nm ultraviolet radiation on the droplet evaporation under various pressures in the atmosphere of dry nitrogen has been studied for a series of homologous alcohols (n-propanol, n-butanol, n-pentanol, n-heptanol, n-octanol, and n-decanol). The alcohol evaporation rates under and without irradiation are calculated. A significant increase in the evaporation rate under low-power radiation is found for higher alcohols, and this growth is shown to be not associated with the heating of a droplet. The obtained results are analyzed by comparing them with experimental data on the slow neutron scattering.
