Airflow and Particle Deposition in Acinar Models with Interalveolar Septal Walls and Different Alveolar Numbers

Figure 7

Comparison of particle deposition between different particle sizes in the 4-alveoli model: (a) total deposition fractions for 0.5–3 µm particles and the time resolution of sectional cumulative deposition for (b) 0.5 µm, (c) 1 µm, and (d) 2 µm. Deposition was quantified in each section of the model, that is, cylinder, the four alveoli (sacs), and the interalveolar pores (necks).
