SOME ASPECTS OF PARTICLE MOTION UNDER CYCLIC FLOW IN REALISTIC HUMAN AIRWAY MODEL
Original language description
Deeper understanding of aerosol transport in human lungs is needed to increase transport efficiency of therapeutic drugs. We investigate a motion of micron-size liquid-aerosol particles in a transparent thin-wall realistic airway model using Phase Doppler Particle Anemometry (P/DPA). A pneumatic mechanism is used to generate cyclic flow of a dilute particle-laden air simulating three distinct sinusoidal breathing patterns. Velocity measurement of monodisperse aerosol particles of di-2-ethylhexyl sabacate (DEHS) is performed in several cross-sections of the airway model in trachea and the first three generations of bronchi. Influence of airway geometry and breathing regimes on the flow field in the airway model is discussed. Mean and fluctuating components of axial velocity during the breathing cycle are evaluated and used for calculation of time resolved axial turbulence intensity in measurement points. Exemplary plots of the mean axial velocity and turbulence intensity are documented
