Computational fluid dynamics (CFD) predictions of inertial particle deposition have not
compared well with data from nasal replicas due to effects of surface texture and the …

Information on the deposition efficiency of aerosol particles in the nasal airways is used for
optimizing the delivery of therapeutic aerosols into the nose and for risk assessment of toxic …

Evaluating the health effects of inhaled submicrometer aerosols, such as combustion
particulate matter and bioaerosols, requires a thorough understanding of transport and …

In this study, a fully unsteady computational fluid dynamics (CFD) model was used and the
transient airflow properties during the entire breathing cycle, including inhalation and …

Information on the deposition of ultrafine particles in nasal airways is important for assessing
the risks of exposure to airborne particulate matter and for understanding drug delivery …

Rodents are routinely used in inhalation toxicology tests as human surrogates. However, in
vitro dosimetry tests in rodent casts are still scarce due to small rodent airways and in vitro …

Based upon available experimental data, a set of empirical equations was derived for nasal
deposition efficiency of inhaled particles in the inertial deposition range for four small …

This study determined the effect of particle size, flow rate, nostril shape, and nasal passage
geometry on nasal particle deposition efficiency (PDE) in ten healthy, nonsmoking adults …

Nasal inhalation helps to protect the lungs from detrimental effects of toxic particles which,
however, may also place the nasal and adjacent tissues at risk. Alternatively, drug–aerosol …

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 …
