Respiratory physiology and pathology are strongly dependent on the airflow inside the nasal
cavity. However, the nasal anatomy, which is characterized by complex airway channels and …

The correlation between aspirin sensitivity, asthma, and nasal polyposis was recognized in
the early 20th century. Today, this classic triad of symptoms, eponymously named Samter's …

The Multiphase Flow Handbook, Second Edition is a thoroughly updated and reorganized
revision of the late Clayton Crowe's work, and provides a detailed look at the basic concepts …

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 …

Background: There are methodological ambiguities in the literature on mesh refinement
analysis for computational fluid dynamics (CFD) modeling of physiologically realistic airflow …

Background A major issue among computational respiratory studies is the wide variety of
nasal morphologies being studied, caused by both inter-population and inter-subject …

Evaluation of nasal spray drug absorption has been challenging because deposited
particles are consistently transported away by mucociliary clearance during diffusing …

In this study, the unsteady airflow field in a realistic model of human upper airways during
the breathing cycle and the fibrous particle transport and deposition were investigated using …

Abstract Treatment of sinusitis by surgical procedures is recommended only when
medication therapies fail to relieve sinusitis symptoms. In this study, a realistic 3D model of …

In the present study, the effects of endoscopic sphenoidotomy surgery on the flow patterns
and deposition of micro-particles in the human nasal airway and sphenoid sinus were …
