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

Figure 3

Instantaneous snapshots of particle positions in the 4-alveoli model during the first cycle after particle inhalation. Particles were 1 µm in diameter. Due to particle dispersion, some particles exited the geometry with expiratory airflow. (a) T = 0.25 s. (b) T = 0.50 s. (c) T = 0.75 s. (d) T = 1.00 s. (e) T = 1.25 s. (f) T = 1.75 s. (g) T = 2.00 s. (h) T = 2.25 s. (i) T = 2.50 s. (j) T = 2.75 s.
