Airborne particulate matter is a diverse pollutant class whose excessive presence in indoor
air contributes to an array of adverse health and material-damage effects. Particles are …

Exposure to fine particulate matter (PM 2.5) is a major contributor to the global human
disease burden. The indoor environment is of particular importance when considering the …

Air distribution in enclosed environments is crucial to thermal comfort and air quality.
Computational fluid dynamics (CFD) has played an important role in evaluating and …

Indoor environmental quality (IEQ) is a critical aspect of the built environment to ensure
occupant health, comfort, well-being and productivity. Existing IEQ monitoring approaches …

Characterization and emission rates of indoor aerosols have been of great interest.
However, few studies have presented quantitative determinations of aerosol particle …

The intake fraction is the attributable pollutant mass inhaled by an exposed population per
unit mass released from a source. In this paper, mathematical models are combined with …

The dispersion characteristics of respiratory droplets are important in controlling
transmission of airborne diseases indoors. This study investigates the spatial concentration …

For non-uniform air distribution, the contaminant accumulation occurs in the stagnant zone
and leads to high exposure risk. A high supply airflow rate increases the air mixing and …

Multizone airflow network models assume that in a zone air temperature and contaminant
concentrations are uniform, and air momentum effects are neglected. These assumptions …

In-duct ultraviolet germicidal irradiation systems are effective systems that are used in
disinfection of pathogenic particles transported by air that moving through the ventilation …
