The invisible made visible: How COVID19 aerosols are ventilated out of large stadia

The COVID-19 pandemic has emphasised the importance of preventing the spread of infected respiratory aerosol particles in crowded spaces, including sports stadiums. Research conducted by Professor Bert Blocken and his teams at Eindhoven University of Technology in the Netherlands and KU Leuven in Belgium has demonstrated how weather conditions affect aerosol particle concentrations, and how these concentrations can be predicted based on weather forecasts.

This work was performed by Bert Blocken and his research teams at Eindhoven University of Technology in the Netherlands and KU Leuven together with partners PlasmaMade, Sport innovator, Johan Cruijff ArenA and Ajax AFC Football Club. It was funded by the Top Sector Life Science & Health (Health~Holland) and by Microsoft and Ansys in the framework of the White House COVID-19 HPC Consortium.
