Airflows in the nasal cavities and oral airways are rather complex, possibly featuring a
transition to turbulent jet-like flow, recirculating flow, Dean's flow, vortical flows, large …

A review of research papers is presented, pertinent to computer modeling of airflow as well
as nano-and micron-size particle deposition in pulmonary airway replicas. The key modeling …

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 …

Considering a human upper airway model, or equivalently complex internal flow conduits,
the transport and deposition of nano-particles in the 1–150 nm diameter range are simulated …

The deposition of ultrafine aerosols in the respiratory tract presents a significant health risk
due to the increased cellular-level response that these particles may invoke. However, the …

The deposition sites of inhaled particles must be known to (1) promote therapeutic effects of
airborne pharmacologic drugs via targeted delivery and (2) improve risk assessments of …

Simulation results of microparticle and nanoparticle deposition patterns, local
concentrations, and segmental averages are contrasted for a human upper airway model …

Laminar-to-turbulent air flow for typical inhalation modes as well as micro-particle transport
and wall deposition in a representative human oral airway model have been simulated …

Airflow patterns within the human upper airways, including nasal airway, oral airway,
laryngeal airway, and the first two generations of tracheobronchial airway, are investigated …

Computational fluid dynamics (CFD) simulations of airflow and particle deposition in
geometries representing the human tracheobronchial tree were conducted. Two geometries …
