Tracking down aerosols

How do infectious aerosols spread in supermarkets, airplanes, and other indoor areas where large numbers of people congregate? Researchers from 15 Fraunhofer institutes and institutions are investigating this in the AVATOR project.

Social distancing and wearing a mask are still the order of the day…

Numerische Simulation der Aerosolausbreitung in einem Klassenzimmer: Eine infizierte Person sitzt in der vorderen rechten Ecke des Klassenzimmers. Die ausgewählte Schnittebene zeigt die Konzentrationsverteilung des virenhaltigen Aerosols. Ein Raumluftreiniger filtert die aerosolbeladene Luft und führt sie gereinigt zurück. © Fraunhofer EMI / Numerical simulation of the aerosol dispersion within a classroom: An infected person sits in the front right corner of the classroom. The selected crosssection shows the concentration distribution of the virus-containing aerosol. A room air purifier filters the aerosol-laden air and returns it purified. © Fraunhofer EMI

Indoor Air: How to Eliminate Viruses Effectively

How can viruses be effectively eliminated from indoor air? This question is still important. Efficient indoor air purification is essential, especially in schools. Fraunhofer researchers are investigating and optimizing various filter and air purification techniques in the AVATOR project.
