In this paper computational modeling of particle transport and deposition in human respiratory tracts is reviewed. Airflow pattern in the upper lung and nasal passages are presented. The Lagrangian trajectory analysis procedure is outlined and its application to nanoand micro-particles transport and deposition are discussed. Sample simulation results for particle deposition are presented and are compared with the available experimental data.
