Relying on benchmark experimental data sets for flow in conduits with local constrictions,
LES and three widely used RANS turbulence models, ie the low Reynolds number (LRN) k …

Time-dependent characteristics of the flow in a human nasal airway constructed from the CT
image of a healthy volunteer were investigated using a computational fluid dynamics (CFD) …

Accurate prediction of respiratory tract deposition is important in gauging the health risks of
ambient bioaerosols and environmental aerosols, as well as in developing pharmaceutical …

As a human grows from birth to adulthood, both airway anatomy and breathing conditions
vary that alter the deposition rate and pattern of inhaled aerosols. However, deposition …

Focusing on the particle deposition due to gravitational sedimentation and inertial impaction,
the transport and deposition of micron particles with various diameters (ie, 1 to 7 μm) have …

Airflow through the nasal cavity exhibits a wide variety of fluid dynamic behaviors due to the
intricacy of the nasal geometry. The flow is naturally unsteady and perhaps turbulent …

Deposition of polydisperse particles representing nasal spray application in a human nasal
cavity was performed under transient breathing profiles of sniffing, constant flow, and breath …

An in vitro study was conducted with the goal of developing empirical correlations to predict
the deposition of particles with an aerodynamic diameter of 0.5–5.3 μm in nasal airways of …

Purpose The purposes of this study were to 1) describe ambient air pollutant concentrations
present during major US marathons, 2) quantify performance decrements associated with air …

Background: Interindividual variability in nasal filtration is significant due to interindividual
differences in nasal anatomy and breathing rate. Two important consequences arise from …
