Realistic transparent human airway model: flow distribution and aerosol transport under steady and unsteady flows

Popis výsledku v původním jazyce

Better understanding of transport, penetration and deposition of particles in the human lungs is needed to comprehend the health effects of atmospheric particulate matter as well as to increase transport efficiency of therapeutic drugs. Comparisons of studies done on idealized lung geometry with investigations made on more realistic models have shown an influence of complex actual geometry and rough airway surface on flow and particle transport. Several works show important difference between particle transport and deposition characteristics under steady and oscillatory flow conditions. To enable optical measurement of aerosol transport with air as working fluid, we created realistic thin-walled transparent airway model. The non-symmetric bifurcation model reflects real non-planar lung geometry and spans from throat to 3rd-4th generation of bronchi. A pneumatic mechanism generated oscillating air flow into the model. Monodisperse aerosol particles were mixed with air at the model entry
