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

Figure 4

Instantaneous snapshots of particle positions in the 4-alveoli model during the second cycle after particle inhalation. All the remaining particles will deposit eventually due to particle interception or gravitational sedimentation. (a) T = 3.25 s. (b) T = 3.50 s. (c) T = 3.75 s. (d) T = 4.00 s. (e) T = 4.25 s. (f) T = 4.75 s. (g) T = 5.00 s. (h) T = 5.25 s. (i) T = 5.50 s. (j) T = 5.75 s.
