Abstract

The understanding of the flow structures and the particle transport/deposition across the human bronchial system remains a challenge to achieve because of the complexity of the geometry of human lungs. This work relies a strong collaboration between physicians, medical imaging researchers, fluid mechanics researcher and CFD researchers. Four configurations of airways (the generic Weibel model, the Human model proposed by Hiroko Kitaoka, a realistic Rat lung obtained by \(\mu \)-CT and a realistic rabbit geometry obtained by a synchrotron based CT) have been generated, meshed and simulated using the CFD commercial package CFD-ACE. Both steady and realistic inflow rates have been studied as well as the associated transport and deposition of particles.
