measured the deposition of ultrafine particles in nasal airway replicas produced by a stereo-lithography machine.Ĭomputer simulation studies of transport and deposition of ultrafine particles in human nasal cavities were reported by Yu et al. suggested an empirical equation for the capture efficiency of the human nasal passage. They also showed that a large part of the airflow passed through the middle and inferior airways.Įxperimental study of deposition of particles in the human nasal passage was reported by Cheng et al.

They constructed their computational model from magnetic resonance imaging (MRI) of a human subject and used the commercial software FIDAP™ in their analysis. In addition, a large portion of inspired airflow passes through the middle and inferior airways, while a smaller fraction passes through olfactory and meatuses regions.Ĭomputer simulations of airflow inside the human nasal passages were reported by Keyhani et al. The common finding of the earlier experimental studies was that the flow regime inside the human nasal cavity for low to moderate breathing rates was laminar. used particle image velocimetry (PIV) on a model fabricated from computed tomography (CT) scans of the nasal passage for their airflow measurements. They found that the airflow in the nose was laminar up to a breathing rate of 24 L/min. Airflow measurements in the nose using hot-wire and hot-film anemometers were reported by Schreck et al. They used a miniature Pitot tube in a nasal cast of a cadaver.
