2021 ME Boehman_Modeling Airflow

A seating chart is studied during an experiment to understand how many infectious aerosol particles others in a classroom expect to inhale under various mitigation scenarios inside 1311 EECS on North Campus in Ann Arbor, MI on Monday, May 17, 2021.

There's a lot we don't know about how these particles behave indoors, but a core conundrum is that while aerosols do not stay within six feet of their source, they're also not uniformly distributed throughout a room.

Using a smoke machine and particle spectrometers, similar to work they've done for the U-M Dental School and Blue Bus, these experiments explore the impacts of different mitigation measures including occupancy limits, masks and increased ventilation.
