Evaporation and Sorption of Toxic Substances in Atmospheric Boundary Layer Flow

Popis výsledku v původním jazyce

This study aims to improve understanding of evaporation of toxic substances into a fully turbulent atmospheric boundary layer and of sorption of these substances on various materials. Very toxic gases such sarin, were considered and an appropriate substituent was found (pentyl acetate). The whole study was conducted in the atmospheric boundary layer wind tunnel and the model scale was 1:50. First the evaporation rate of pentyl acetate from the free surface was measured, than the concentration field around a building and a cylinder (a model of a person), and the sorption of the substance to the surfaces of the building and the cylinder. The surface materials varied from an external wall plaster to different tissues using for protective suit manufacturing. The sorption is significantly influenced by the air moisture, but general behaviour like no sorption on the airproof materials (e.g. teflon) and best sorption on the active carbon tissue were recognised.
