| Summary: | 碩士 === 國立成功大學 === 航空太空工程學系 === 103 === A comprehensive three-dimensional numerical model was developed to study the gas-solid flow behaviors in asthmatics or normal airway by using Weibel’s lung model. The transient gas phase was modeled with laminar computational fluid dynamics (CFD) and the particle phase was modeled with discrete phase model (DPM). In this paper, the flow structure and particle deposition pattern for normal and asthmatic airway bifurcation are compared and discussed. The numerical results reveal that the inertial force and the position of secondary flow are the main reason cause particles deposition.
