Robert Kunz wrote in about his work titled "Modeling of Oxygen Uptake and Particle Deposition in the Human Lung using Homogeneous and Two-Fluid Models".
Researchers at Penn State University
Applied Research Laboratory (USA), Center
for Medical Diagnostic Systems and Visualization (Germany), and Image Processing Laboratory, Institute
of Anatomy and Cell Biology (Germany), are using modern medical imaging
technology and three-dimensional, time accurate multiphase CFD to model oxygen
uptake and particle deposition in the human respiratory system.
A physically accurate representation of the trachea and most of the convective regime bronchi (up to generation 13) are obtained using high-resolution computed tomography (HRCT) of a rubber cast of an adult human tracheobronchial tree (Fig. 1). A triangulated model of this data is used as a bounding surface for hybrid unstructured meshes generated using the ICEM CFD 4.2 package.
