Industries such as metallurgy, chemical engineering, metal products, building materials,
welding, and nuclear engineering inevitably emit high-strength pollutants (solid and liquid …

Background and objective Human upper airway (HUA) has been widely investigated by
many researchers covering various aspects, such as the effects of geometrical parameters …

Abstract Directly using CFD (Computational Fluid Dynamics) for ventilation prediction and
control is time-consuming and data-storage-expensive. Construction of linear system is of …

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

To address the problem of airborne transmission caused by droplets/droplet nuclei
containing infectious viruses such as influenza A, tuberculosis, and SARS-CoV-2, the …

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 …

Background and objectives Suspended respirable airborne particles are associated with
human health risks and especially particles within the range of ultrafine (< 0.1 μm) or fine (< …

In this study, flow field characteristics in the trachea region in a realistic human upper airway
model were firstly measured by particle image velocimetry (PIV) in the air under three …

Several mathematical models of human thermoregulation have been developed,
contributing to a deep understanding of thermal responses in different thermal conditions …

Infectious respiratory diseases have long been a serious public health issue, with airborne
transmission via close person-to-person contact being the main infection route. Coughing …
