Simulation of Virus Aerosol Processes

These researchers are studying the effect of UV-C radiation on virus aerosols’ infectivity. They use computational fluid dynamics (CFD) packages to calculate aerosol movement inside an environmental chamber, combining the aerosol paths and velocities with three-dimensional UV-C intensity contours to solve the UV-C dose received by each individual virus aerosol. Use of the CFD packages could also calculate aerosols’ residence times inside the chamber before they have been collected by samplers. Knowing the residence time is indispensable to determine how the environmental conditions affect virus aerosols’ viability and infectivity. Aerosol sampling processes will affect the flow field inside the environmental chamber, so studying the sampling location’s effects is important for choosing the optimal sampling locations during the experiment.
