Pathogen droplets released from respiratory events are the primary means of dispersion and
transmission of the recent pandemic of COVID-19. Computational fluid dynamics (CFD) has …

Laser-induced graphene (LIG) is uniquely positioned to advance applications in which
electrically conductive carbon coatings are required. Recently, the antifouling, antiviral, and …

The application of ultraviolet germicidal irradiation (UVGI) technology inside the heating,
ventilation, and air-conditioning (HVAC) air ducts to purify circulating air and improve indoor …

With the renewed focus on indoor air quality (IAQ) due to “Sick building syndrome” and the
recent COVID-19 pandemic, the availability of innovative components and innovative …

In order to refine the CFD methodology for predicting particle fate in duct flows, this study
investigated four key issues largely influencing the predictive accuracy. The flow field …

Due to the global outbreak of infectious diseases over the years, airborne pathogen removal
from the indoor environment has become a critical issue. Ultraviolet germicidal irradiation …

This paper aims to review the engineering controls for indoor air quality (IAQ) from a systems
design perspective. As a result of the review, we classify the literature content into three …

Attaching ribs on duct walls is an effective way to improve the inactivation efficiency of in-
duct UVGI systems (ID-UVs), and this study explored the optimal rib design. The Critical …
