Knowledge regarding particle deposition processes in the nasal cavity is important in
aerosol therapy and inhalation toxicology applications. This paper presents a comparative …

Understanding the particle exposure characteristics in human respiratory airways plays
important roles in assessing the therapeutic or toxic effects of inhaled particles. In this study …

A 3D computational model was developed to study the flow and the transport and deposition
of nano-size particle in a realistic human nasal passage. The nasal cavity was constructed …

A computational model was developed for studying the flow field and particle deposition in a
human upper airway system, including: nasal cavity, nasopharynx, oropharynx, larynx and …

The transport and deposition of nanoparticles, ie, dp= 1–2 nm, or equivalent vapors, in the
human nasal cavities is of interest to engineers, scientists, air-pollution regulators, and …

The breathing region connects the nasal cavity with the outside environmental air where
flow is accelerated through the nostrils. Particles introduced into the nasal cavity without …

To gain a better understanding of nanoparticle exposure in human nasal cavities, laboratory
animals (eg rat) are used for in vivo studies. However, due to anatomical differences …

Background and objective From various perspectives (eg inhalation exposure and drug
delivery), it is important to provide insights into the behavior of inhaled particles in the …

Computational fluid dynamics (CFD) simulations were conducted in a model of the complete
nasal passages of an adult male Sprague-Dawley rat to predict regional deposition patterns …

Ultrafine particle deposition studies in the human nasal cavity regions often omit the
paranasal sinus regions. Because of the highly diffusive nature of nanoparticles, it is …
