- Formulation of a comprehensive rheological description of complex fluids expelled from nose and mouth in the case of various expiratory events
- To study numerically the spreading and adsorption of complex fluids and aerosols in filter layers of protective masks.
- To propose innovative designs of fibrous microstructures of protective masks to increase mask efficiency.
Methodology and research questions
- Multiphase lattice Boltzmann framework with a pseudo-potential method to reproduce the interface for droplets (CTH)
- CFD (DNS) for Aerosols (LTU)
- Fibrous microstructure of real masks as a computational domain e.g. using X-ray tomography (LTU)
- Focus on the following effects:
1.Microstructure of fibrous mask materials (local geometry)
2.Wettability properties of mask material (influence of contact angles)
3.Newtonian and non-Newtonian nature of complex fluids during expiratory events
4.Aerosol transport through mask material
