A total deposition fraction of 76 90% was calculated, with the majority of aerosol deposited in the ET region or upper airway (75 84%), and small but not insignificant deposition (2 6%) in the lower airways (TB and pulmonary region).
At the maximum deposition zone, this model predicts 0.47 in.
In addition, for Ti 6Al 4V the deposition efficiency averages 93% and the maximum deposition rate is 1.8kg/hh.
Arc spraying has the maximum deposition rate, with rates of 15 kg/h or higher.
The pressure drop and deposition fraction follows a linear relation for sandstone cases, whereas for the sawdust cases, the pressure drop is sensibly invariant with time although a noticeable increase in deposition fraction with time is realized.
The maximum deposition rate reached was 0.35 μm/min due to a high ion bombardment.
The maximum deposition rate for spray arc GMAW is relatively high about 60 mm/s (150 in/min).
The deposition fraction constant a (h 1) was calculated for each ENM-media combination.
We estimated lung deposition of PM for each specific exposure using mouse tidal volume, breathing frequency, and an estimated deposition fraction.
The number deposition fraction increased as particle size decreased, reaching 0.84 +/- 0.03 for the smallest particles (midpoint CMD = 8.7 nm).
