Study of aerosol transport and deposition in the lungs using computational fluid dynamics (CFD)

Ertbruggen, Caroline van 20 June 2005 (has links)
We have studied gas flow and particle deposition in a realistic three-dimensional model of the bronchial tree, extending from the trachea to the segmental bronchi (7th airway generation for the most distal ones) using Computational Fluid Dynamics (CFD). The model is based on the morphometrical data of Horsfield et al. [J. Appl. Physiol. 31: 207-217, 1971] and on bronchoscopic and CT images, which give the spatial 3D-orientation of the curved ducts. It incorporates realistic angles of successive branching planes. Steady inspiratory flow varying between 50cm³/s and 500cm³/s was simulated as well as deposition of spherical aerosol particles (1 to 7& / Doctorat en sciences appliquées / info:eu-repo/semantics/nonPublished
