Description	Transport of aerosol particles in respiratory tract attracts more and more attention in view of tar-geted delivery of therapeutic sprays to treat wide spectrum of not only pulmonary diseases. 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 mecha-nism generated oscillating air flow into the model. Monodisperse droplets were mixed with air at the model entry. Velocity and size measurement of the particles were done using Phase/Doppler Particle Analyzer (P/DPA). Difference between air supply from the %22mouth side%22 and the %22alveoli side%22 into simple bifurcation lung model was investigated. We observed increased turbulence intensity especially during expira-tion phase in case of the mouth side control compared to alveoli side control.
