Numerical simulation of flow structure and deposition of particles in Asthematic Airway Bifurcation

Symmetric airways bifurcation corresponding to generation 12-23 of Weible’s model will be investigated through numerical simulation. Parent’s airway segment is modeled as a smooth circular tube while the child segment is to be considered as asthmatic airway bifurcations. The effect of size of the lumen area and number of folds on particle deposition and pressure drop will be investigated. The present work extends to deal with asymmetric airway extracted from 2-3 branches of the model of Weible’s in order to more appropriately model human air passage.
