Recent work in our three groups focuses on the understanding of:
1) Fluids and porous materials interractions
Multiscale analysis of heat, mass, biological, chemical and poromechanical behavior of porous materials
Up-scaling material models for urban microclimate analysis (vegetation, trees) >>>more
2) Urban microclimate
Multiscale models of urban heat island, micro and local climate and comfort
Urban microclimate and building energy
Urban microclimate and climate change >>>more
3) Granular media
DEM modeling of stick slip of granular media for dynamic earthquake triggering
DEM modeling of instabilities of wet granular media
Active and passive acoustic probing >>>more
Methods and approach
Our scientific approach is based on the coupling of advanced experimental and computational methods.
Multiscale approaches are developed to adequately capture the different phenomena at play at different scales.
Techniques used are:
advanced experimental high resolution time resolved techniques (neutron and X-ray imaging, etc.)
Wind and water tunnels with time-resolved PIV/LIF
High performance multiscale computational modeling for porous media, buildings, urban environment, vegetation.
Computational approaches: MD, DEM, LBM, pore network, CFD, FEM,
The research is in strong collaboration with ETH Zurich, chair of building physics.
