Virus-laden droplets dispersion may induce transmissions of respiratory infectious diseases. Existing research mainly focuses on indoor droplet dispersion, but the mechanism its and exposure in outdoor environment is unclear. By conducting CFD simulations, this paper investigates evaporation transport solid-liquid an open environment. Droplet initial sizes (dp = 10 μm, 50 100 μm), background re...
