New translation : Airstream trajectories in an image-based model of the proximal part of the human tracheobronchial tree


Thorax images were acquired by multislice helical x-ray tomography. Thoracic images are then processed to reconstruct the geometry of the trachea and the six first bronchus generations and to virtually travel inside this duct network. The facetisation associated with the three-dimensional reconstruction of the tracheobronchial tree is improved to get a computation-adapted surface triangulation, which leads to a volumic mesh composed of tetrahedra.

A computational model of an oscillatory laminar flow of an incompressible Newtonian fluid (rest breathing) has been carried out.

The Navier-Stokes equations associated with the classical boundary conditions and different values of the flow dimensionless parameters are solved using the finite element method.
