Abstract
To better understand the human pulmonary system and governing aerosol deposition mechanisms within the lung, an accurate description of the airflow in the conductive and respiratory pulmonary airways is considered to be essential. In-vivo measurements are deemed impossible due to the small scales in the lung structure. Though numerical simulations can improve the insight, validation of the results is mostly lacking, especially in the extraction of particle trajectories. Numerical and experimental studies have been performed at the von Karman Institute for Fluid Dynamics on single and multiple bifurcation models representing simplifications of the lung system. Both steady and oscillating flows have been studied for the upper lung airways, while steady flow conditions were imposed in the modeling of the alveolar zones. Further experiments consisted in the extraction of particle trajectories in the models of the respiratory airways. This chapter presents an overview of the conducted measurement campaigns complemented with the main observations and results.
