In this study, a computational model was developed and the airflow and particle transport patterns in a human nose were studied. The geometrical model for the nose was created based on nose sections generated by Magnetic Resonance Imaging (MRI) of a human subject. The airflow fields were simulated for several breathing rates and deposition of particles with different aerodynamic diameters was analyzed. The results showed that the deposition rate of particles increases as the particle diameter increases. Furthermore, the deposition rate also increases as the breathing rate increases.
