Vliv vývoje plic u novorozenců a dětí na charakteristiky proudění a depozici aerosolů – výpočtové modelování a experimentální validace

Období řešení: 01.01.2020 — 31.12.2022

O projektu

The proposed project will focus on the flow field and aerosol transport and deposition in developing infants and children respiratory tract to elucidate whether and how different breathing profiles will impact on the aerosol deposition. Several age groups of infants and children ranging from several weeks until 5 year will be studied in vitro and in silico using computational modelling and experiments. For computational modelling several model will be used, namely RANS models, Large Eddy Simulation and Direct Numerical Simulation. Classical CFD codes based on control volumes will be used linked with Euler-Lagrange and Euler-Euler approach for particles tracking. Also lattice Boltzmann technique in cooperation with Karlsruhe lattice Boltzmann group in Germany will be applied and further developed for LES and DNS simulations. Experimental research will use a unique breathing simulator and several optical diagnostic methods like PDA, LDV and fluorescence technique for particles deposition.
