Abstract

The purpose of this paper (Part 3) is to investigate flow patterns and contaminant distributions in the human respiratory tract using 3-dimensional computational fluid dynamics analysis. Numerical airway models were generated reproducing detailed respiratory tract geometries using CT (Computed Tomography) data and CFD (Computational Fluid Dynamics) simulations that replicate e-cigarette smoking conditions. Complicated flow patterns and non-uniform contaminant concentration distributions were formed within the numerical airway models and the individual specificity was also confirmed.
