Fig. 5: Influence of the emitter stage position (actor), 50% reduced airflow rate and checkerboard pattern seating arrangement on individual (PCFD) and global risk of infection (RCFD) at the venue with displacement ventilation (DVV) for a silent passive emitter.
Infection risk plots for the stage (actor) (I) compared to the audience emitter position B9 (II) for the silent passive emitter are shown: (a) standard conditions with full air flow rate (4500 m³/h) and occupancy rate (99 spectators), (b) 50% reduced air flow rate and (c) checkerboard seating arrangement. The individual risk of infection is plotted for each position, except for the red positions, as these do not represent seats in the audience. The sum of risks for each venue and emitter position as well as the number of spectators with the acceptable risk of infection Racc > 1% are indicated above the plots.
