Example particle trajectories for 0.4 m s−1 freestream velocity and moderate inhalation simulations for 7 µm particles at orientations (a) 90°, (b) 135°, and (c) 180° relative to the oncoming wind. Each image shows 20 particles released upstream with the top particle 0.02 m higher than the bottom one.
