摘要

In this paper numerical flow predictions within natural airway geometries are presented. The simulations are enabled using an Immersed Boundary approach, which is briefly described. The focus is set on analysing and discussing the flow physics in dynamic as well as in static healthy and injured porcine airways. The results show that the surface deformation has a significant influence on the flow phenomena. Due to negligible geometrical changes of the injured airways, only minor differences of the flow field could be observed, while comparing the results with the healthy airways.
