摘要：A lung deposition model for fibrous aerosol needs accurate deposition equations for different regions of the human respiratory tract. For fiber deposition in the tracheobronchial region there are veral theoretical and empirical equations to predict deposition efficiency in the impaction-dominant region. However, few were verified with experimental data. We have obtained experimental data of fiber deposition in realistic human airway replicas using carbon fibers. Comparison of experimental dat
a and existing deposition models yield variable results, with some models performing better than other models. There was no consistent agreement found over the Stokes number range of experimental data. A generic empirical model for fiber deposition in the tracheobronchial region was developed bad on all carbon fiber deposition data in 幼儿绘本阅读
