Experimental study of aerosol transport in semi-realistic human airway model
Original language description
In vitro studies of aerosol transport in human airway models give considerable information for advancement of targeted drug delivery and serve for validation of numerical simulations where more accurate turbulence models are needed. We applied a semi-realistic transparent model of human airways for a study of flow of micron-sized spherical particles dispersed in air using Phase Doppler Anemometry (PDA). The model is based on CT scans of human lungs and encompasses mouth cavity, realistic glottal geometry and three to four generations of bronchi with 3D branching. Cylindrical tubes were used to replace original rough and warped walls of airway channels. 1D PDA with classical optics was used for measurement of time-resolved velocity of particle-laden airflow in multiple points of the optically transparent model. Aerosol particles of DEHS with 3 um in diameter were produced by CMAG, mixed with air in a static mixer and resulting dilute dispersed two-phase mixture was led to the lung mode
