title: Impaction and sedimentation deposition of fibers in airways.
abstract: Theoretical impaction and sedimentation deposition of fibers in a model airway have been obtained based upon Jeffery's theory of particle motion. The corresponding expressions for the equivalent diameter of fibers have also been derived. The results are compared with experimental data and other formulas available in the literature for glass fibers. It is shown that for the flow condition existing in the airways, the equivalent diameters of fibers for both impaction and sedimentation are very close to the values obtained when the fibers are oriented parallel to the flow.
