Complex fluids, colloids and condensed matter

By combining battery, electric machine, power electronics and mechanical transmission, the electric vehicle is an example of an application that combines a range of constraints for the formulation of technical fluids. In recent years, there has been renewed interest in the study of the latter for the transport sector...

In the context of the energy transition, it is expected that oil production will decrease at the same pace as the development of low-carbon energies and people’s evolving needs in this area...

​​​​​​​Numerous IFPEN applications, from liquid-liquid extraction for biofuel production to the flotation process for the separation of microplastics, bring into play interactions between a fluid and the large number of inclusions (bubbles, drops) it contains...

IFPEN uses numerous fluids in its fields of innovation for a variety of applications, ranging from renewable energy production to sustainable mobility. Many of the fluids are complex mixtures and the chemistry of their components (hydrocarbons, alcohols, esters, etc.) varies depending on the target application: combustion, cooling, lubrication, electrical insulation, etc.

The transport of colloidal particles in porous media is relevant to a number of fields, including geosciences and environmental engineering. Particle-matrix interactions can lead to deposit formation and accumulation, potentially damaging the medium and altering its permeability. (...) At IFPEN, the problem was originally studied for oil and gas production, but research has now been extended to include the fields of geothermal energy and geological storage of CO2.
