Modeling airflow and filtration reveals truths and misconceptions on commonly held beliefs about virus spread
The interior of an airplane is perhaps one of the safest places to be when it comes to avoiding contamination from a virus like COVID-19. This is one of the surprising findings arising from detailed studies of recent so-called “super spreader” events in combination with computational fluid dynamics (CFD) modeling. Together, they highlight the need …
