Objectives For dry powder inhalers, the airflow properties in the airways could affect the
deposition of inhaled particles; the flow patterns vary inherently between patients. This …

ABSTRACT A three-dimensional model of the larynx was created based on morphometric
measurements of replica human casts. The larynx is simulated as a 6-cm-long cylinder with …

This paper focuses on the impact of including nasal cavity on airflow through a human upper
respiratory tract. A computational study is carried out on a realistic geometry, reconstructed …

Toxic nanoparticles, also called ultrafine particles, pose a significant risk to human
respiratory health. During inhalation, toxic particles may escape to the lower generations of …

A comprehensive understanding of airflow characteristics and particle transport in the
human lung can be useful in modelling to inform clinical diagnosis, treatment, and …

The flow mechanisms that play a role on aerosol deposition were identified and presented in
a companion paper (Timothy et al. in Med Biol Eng Comput. doi: 10.1007/s11517-015-1407 …

Background Obstructive upper airway pathologies are a great clinical challenge for the
airway surgeon. Protection against acute obstruction is critical, but avoidance of …

Airflow into the lung is the result of negative alveolar pressure caused by the simultaneous
action of diaphragm contraction and rib cage expansion. However, all of the determinate …

A number of in vivo, in vitro and numerical studies have considered flow field characteristics
and micro-particle deposition in the oral airway extending from the mouth through the larynx …
