Particle deposition in the small bronchial tubes (generations six through twelve) is strongly influenced by the vortex-dominated secondary flows that are induced by axial curvature of the tubes. In this paper, we employ particle destination maps in conjunction with two-dimensional, finite-time Lyapunov exponent maps to illustrate how the trajectories of(More)
The flow fields in lower lung airways are rich in secondary flows in form of vortices. These vortices are known to impact the micro-particle transport in lung airways. The complex geometry of lung airways plays a significant role on the secondary flows generation. Inhaled air temperature may also have an impact on the bronchial tube flows and therefore to(More)
