The outbreak of the coronavirus disease has drawn public attention to the transmission of
infectious pathogens, and as major carriers of those pathogens, respiratory droplets play an …

Displacement ventilation is a buoyancy-driven air distribution strategy exploiting the
convective heat sources' thermal plumes to push the contaminants towards the ceiling. This …

Screening patients for potential respiratory infections through nucleic acid sampling was a
critical non-pharmacologic intervention during a respiratory infectious disease pandemic …

The breathing zone of an individual indoors is usually defined as a finite region steadily
formed in front of a face. Assuming the steady formation of the breathing zone, we propose a …

The furniture layout between two people complicates the interaction between indoor airflow,
human thermal plume, and exhalation flow in the breathing microenvironment. It thus …

COVID-19 virus can replicate in the infected individual's larynx independently, which is
different from other viruses that replicate in lungs only, eg SARS. It might contribute to the …

With increasing reliance on daycare centers for early childhood development, ensuring
healthy environments in semi-enclosed baby beds for nap** is crucial, given infants' …

This paper presents a framework for applying Computational Fluid Dynamics (CFD) to study
indoor air quality in a classroom environment by analysing the transport and extent of …

Considering pollutants sourced from one's own exhaled air and skin as well as ambient air,
this study adopts CFD technology to explore accurate evaluation method of inhalation …

Understanding the influence of the human body's thermal plume on exhaled airflow is
