Predicting the dry deposition of aerosol‐sized particles using layer‐resolved canopy and pipe flow analogy models: Role of turbophoresis

[1] A number of synthesis activities, mathematical modeling, and experiments on dry deposition of aerosol‐sized particles over forested surfaces point to three disjointed findings: (1) deposition velocities measured over tall forests do not support a clearly defined minimum for particle sizes in the range of 0.1–2 mm; (2) when measurements of the normalized deposition velocity (Vd ) are present...

Deposition of submicron charged particles in turbulent pipe flow with an application to the trachea

The paper presents a study of the deposition of submicron charged spherical particles caused by convection, Brownian and turbulent diffusion in a pipe with a smooth wall and with a cartilaginous ring wall structure. The model is supposed to describe deposition of charged particles in generation 0 (trachea) of the human respiratory airways. The flow is modeled with a SST-turbulence model combine...

A simple mechanistic model of deposition of water-soluble aerosol particles in the mouth and throat.

Aerosol drugs are usually delivered to the lung by inhalation via the oral route, since aerosol deposition is much lower in the oral than in nasal airways. In the present study a practical, non-CFD-based, mechanistic model is developed, which permits an efficient calculation of deposition along the oral route with simple computational means. A simplified geometrical description of the mouth and...

Deposition and retention of ultrafine aerosol particles in the human respiratory system. Normal and pathological cases.

The particle number concentration in ambient air is dominated by nanometer-sized particles. Recent epidemiological studies report an association between the presence of nanoparticles in inhaled air at the workplace and acute morbidity and even mortality in the elderly. A theoretical model of deposition of 20 nm particles in the human alveolus was formulated. Gas flow structure and deposition ra...
