Simulation of fluid dynamics and particle transport in realistic human airways

TL;DRAbstract

The aim of this research is to numerically study the flow characteristics and particle transport within human airways, specifically, the upper airways starting from the trachea to major bronchi. Different entering flow rates and frequencies are the major parameters varied in order to analyze the effect on particle deposition. There have been numerous flow-particle studies in human airways at the current level of knowledge, but one major contribution from this research is that realistic geometries of human airways are used to study flow-particle interaction, in which the airway models are reconstructed from computerized tomography (CT) data of real human tracheobronchial airways.<br><br>CFD techniques for this particular study are developed based on the literature review of other similar studies. The k-omega turbulence model was found to be suitable for this type of study. Evaluation and validation of the numerical approach and results were carried out by comparing with other experiment
