Figure 5

Deposition efficiency (DE) of 3–25 µm particles injected under steady conditions (Q = 6 L/min). RUL and RLL are the right upper and lower lobes, LUL and LLL are the left upper and lower ones. DE in the upper airways is presented as a function of the impaction parameter IP (Eq. 1), while the Stokes number (Eq. 7) better represents the DE behaviour in downstream regions.
