Fluid Interfaces

When immiscible fluids come into contact, their interface is the object of a large number of phenomena linked in particular to the physico-chemical nature of the fluids, whether liquid or gaseous. The presence of solid surfaces or fibres, particularly with temperature differentials, adds further possibilities of physical mechanisms to be studied.

LadHyX has been conducting fundamental and applied research for several years on soft matter, wetting, capillarity, drops and bubbles. Work on surface waves, wakes, wave turbulence, wave resistance and wave generation by the wind can lead to the optimisation of shapes at interfaces or the study of biolocomotion.

In the presence of solid surfaces and fibres, investigations around textiles, their wetting and capillary adhesion allow to understand and optimise aerosol capture or fog collection.

Finally, when a drop impacts a surface, cold or hot, a phase change can occur leading to icing or calefaction and producing physical phenomena studied theoretically, numerically and experimentally.
