The group’s research are focused on interfacial heat and mass transfer between fluids and solid walls by taking into account evaporation, condensation or solidification, dispersed flows including turbulence/particle interactions, the dynamics of granular media and active particle suspensions, and the stability and transition to turbulence of fluids with complex rheology. In these areas, theoretical, experimental and numerical works are carried out . Through multi-scale approaches, the group develops advanced measurement techniques to address :
- Heat and mass transfer mechanisms in droplets and sprays (multiband laser-induced fluorescence imaging, spatially and temporally resolved).
- The relationships between microstructures/macroscopic behaviour (suspension and granular media)
- The behaviors of complex fluids in reactive flows.
- The nano/microstructure/macroscopic behaviour links for a fine description of the (thermo)mechanical properties of polymeric materials and solid composites.
