Design of optical cavity for air sanification through ultraviolet germicidal irradiation
The transmission of airborne pathogens represents a major issue to worldwide public health. Ultraviolet light irradiation can contribute to the sanification of air to reduce the pathogen transmission. This study concerns the design of a compact filter for airborne pathogen inactivation by means of UV-C LED sources, whose effective irradiance is enhanced thanks to high reflective surfaces. Ray-tracing and computational fluid dynamic simulations are both used to model the device and to maximizedoi:10.1101/2021.03.04.21252517 fatcat:tz6hpvrdgzagxnv5fgurzt4jwe
