Modeling of inertial particle transport and deposition in human nasal cavities with wall roughness
JOURNAL OF AEROSOL SCIENCE, 38(4), 398–419.
author keywords: human nasal cavity; inertial particle decomposition; computer analysis; wall roughness
TL;DR:
Considering drug–aerosol targeting, an optimal impaction parameter value exists which generates for normal inlet conditions the largest deposition in desired areas, e.g., the middle meatus, inferior meatus and olfactory regions, however, the absolute deposition efficiencies are very small because particles hardly reach those regions due to the complex nasal geometric structures.
