Mathematical model based on the radiosity method for estimating the efficiency of in-duct UVGI systems

[EN] The article describes a model for calculating the killing ratio of different pathogens with an in-duct ultraviolet (UV) device. The model is based on the radiosity method adapted for the UV radiation range and can be used for analyzing any lamp distribution. The paper provides the necessary vie...
