Using Particle Tracking to Optimize Indoor Air Quality
During the COVID-19 pandemic, we’ve seen an increased focus on indoor air quality – especially regarding the spread of infectious diseases in all types of indoor environments. Since one path of transmission is through exhaled droplets both large and small, the engineering community is particularly interested in how those particles move in indoor environments.

High demands are placed on modern HVAC systems to create optimal indoor environments while minimizing energy usage. Consequently, usage of computer-based analysis tools like computational fluid dynamics (CFD) that aid in the design of these systems is becoming more prevalent. With the recent addendum to ASHRAE 62.1 we expect the demand for CFD analyses to increase even further. The change states that a CFD analysis can be used to estimate the ventilation effectiveness value used to determine the outdoor air requirement instead of tables provided in the standard.
