Original abstract

The effort to understand how aerosols transport and deposit in lungs drove us to application of particle velocity measurement with P/DPA (Phase Doppler Particle Anemometry). We used optically transparent realistic human airway model and liquid aerosol for experiments under steady and cyclic breathing conditions. The aerosol diameter and breathing conditions were varied during experiments. Velocity and turbulence intensity of aerosol particles in several airway positions at the steady and cyclic breathing conditions are shown and analysed in the paper. This work is a follow-up of air flow distribution study performed by our group earlier.
