Toward the modeling of mucus draining from the human lung: role of the geometry of the airway tree.

Archive ouverte | Mauroy, Benjamin | CCSD

International audience. Mucociliary clearance and cough are the two main natural mucus draining methods in the bronchial tree. If they are affected by a pathology, they can become insufficient or even ineffective, t...

Lumen areas and homothety factor influence airway resistance in COPD

Archive ouverte | Bokov, Plamen | CCSD

International audience. The remodelling process of COPD may affect both airway calibre and the homothety factor, which is a constant parameter describing the reduction of airway lumen (h(d): diameter of child/parent...

Interplay between geometry and flow distribution in an airway tree.

Archive ouverte | Mauroy, Benjamin | CCSD

International audience. Uniform flow distribution in a symmetric volume can be realized through a symmetric branched tree. It is shown here, however, by 3D numerical simulation of the Navier-Stokes equations, that t...
