Experimental and CFD Simulations of the Aerosol Flow in the Air Ventilating the Underground Excavation in Terms of SARS-CoV-2 Transmission

The paper presents the results of experimental and model tests transport dispersed fluid droplets forming a cloud aerosol in stream air ventilating selected section underground excavation. excavation for testing is part ventilation network Experimental Mine Barbara Central Mining Institute. For given environmental conditions, such as temperature, pressure, relative humidity, velocity air, distribution droplet changes mixture water vapor along at distance was measured 10 m, 25 50 m from source its emission. emission space nozzle that located inlet (inlet) obtained situ were related to numerical calculations using computational dynamics (CFD). Numerical performed Ansys-Fluent Ansys-CFX software. dimensions geometry under investigation are presented. authors describe adopted assumptions conditions discuss solution.
