Deposition of length-classified glass fibers in a replica of human airways

abstract

en

Inhalable fibers form a specific group of particles, which are provably, or potentially toxic for humans [1]. A few studies applied computational fluid and particle dynamics (CFPD) calculations for prediction of localised deposition of fibers. However, obtaining reliable experimental data for validation represents significant problem for all teams performing numerical simulations. A realistic replica of human airways has been developed at Brno University of Technology. The identical geometry exists as a physical replica for experimental work and as a digital geometry for numerical simulations. In this contribution we introduce measurement of deposition of length-classified fibers.
