The nature and airborne dispersion of the underestimated biological agents, monitoring,
analysis and transmission among the human occupants into building environment is a major …

Analyzing multiple physical factors simultaneously to determine optimal ventilation solutions
can be challenging. Furthermore, this type of analysis needs a large case number to be …

Personalized air curtains promise to reduce respiratory exposure in industrial environments.
This work explored the performance of normal safe helmets equipped with air curtains to …

An air curtain is an aerodynamic barrier for regional isolation and protection; however,
research on its application in ventilated rooms is insufficient. This study investigated the …

An air curtain is an aerodynamic barrier for contaminants and is frequently installed in the
doorway to separate indoor and outdoor spaces. There are few studies on the isolation of …

Infectious respiratory diseases are known to have high levels of airborne transmissibility.
However, traditional ventilation methods based on perfect mixing often lead to the diffusion …

Formaldehyde (HCHO) is a well known carcinogen. While most studies investigate emission
from wood-based materials, knowledge about releasing of HCHO by natural gas combustion …

Infectious diseases (eg, coronavirus disease 2019) dramatically impact human life, economy
and social development. Exploring the low-cost and energy-saving approaches is essential …

This study proposes the integration of a localized-chair exhaust (LCE) device and a
downward piston ventilation (DPV) in an educational space. The main aim is to assess the …

To mitigate the risk of airborne transmission during close patient-doctor interactions in
general consulting ward, a novel personalized air curtain (PAC) system is proposed to …
