Experimental and Computational Modelling of Aerosol Transport Using the BUT Benchmark Human Lung Model

journal article - other

en

The aerosol team at the Brno University of Technology (BUT) has continuously developed a realistic human lung model and has used it for aerosol transport studies since 2006. The model was originally based on the digital reference model of [1] and contained airways from the throat down to the 7th generation of branching. It was gradually extended on the upper part with the mouth and nasal cavity. Also, its simplified versions were designed for specific research applications (Y-shaped model, semirealistic model). It was fabricated in two forms, as a transparent model for optical flow measurements and segmented for deposition testing. Originally it was ventilated using a single-cylinder breathing simulator that was later updated to a 5-piston breath generator which enables prescription of the individual course of breath for each lung lobe. The paper summarises up to date results acquired with different versions of the BUT model and gives examples of the outcomes acquired by several teams throughout Europe, including the COST Siminhale collaborators. Selected flow and deposition results were published in the Ercoftac database.
