Determine the aerodynamic properties of Legionella pneumophila for a drag force expression

Brief:

As water distribution system is an epidemiologic reservoir for nosocomial outbreaks of Legionnaires’ disease, understanding the dispersion and deposition of Legionella-containing aerosols from water appliances in buildings is important. This study determines the aerodynamic properties of Legionella pneumophila to demonstrate the adaptation of a novel drag force expression which has been recently proposed to enhance the accuracy of Computational Fluid Dynamics (CFD) simulation of bioaerosol deposition. The study also shows that the deposition patterns of Escherichia coli - a species with morphological characteristics similar to Legionella pneumophila in ventilated enclosure - are useful for studying the pathogenic mechanisms in Legionnaires’ disease.
