Présentation

I am a Professor in Fluid Mechanics at the University Claude Bernard Lyon 1 (UCBL). I teach in the Department of Mechanics of Polytech Lyon, the engineering school of the university, and in the bachelor/master programs of the Department of Mechanics of the university. I am a researcher at the Laboratory of Fluid Mechanics and Acoustics (LMFA), a mixed research unit across École Centrale Lyon, UCBL, INSA and CNRS (UMR5509).

RESEARCH – FLUID MECHANICS

With my research group, we develop models for fundamental and practical flow phenomena in industrial, environmental and geophysical applications. These models are inspired and validated by lab experiments and numerical simulations. See my research website for more details.

1) The fluid mechanics of cleaning and decontamination of surfaces

Keywords: mass transfer, convection, multiphase flows, multi-physics, interfacial phenomena. We analyze and model the impact on the cleaning rate of flow and liquid properties, confinement (boundary layers, thin films, geometry), porous and absorbent materials, chemistry (solubility, reactivity, surface tension). Applications: surface cleaning, decontamination of toxic biological, chemical and radioactive contaminants and disease transmission.

2) Drag reduction with flows over superhydrophobic surfaces

Keywords: surface flows, superhydrophobic surfaces, surface drag, multi-scale, interfacial phenomena, surfactants, Marangoni stresses, laminar/turbulent. We study how laminar or turbulent flows over superhydrophobic surfaces are affected by surface texture, flow properties and surfactants. Applications: drag reduction in maritime shipping, pipe flows and microfluidic devices.

3) Surfactant-driven flow dynamics in confined geometries

Keywords: surface flows, surfactant, Marangoni flows, interfacial phenomena, thin film flows, Stokes flows, geometrical confinement. We model how surfactant molecules can affect macroscopic flows, such as flows over superhydrophobic surfaces, thin film flows, near contact lines or in confined geometries. This fundamental research supports our research on surface cleaning and superhydrophobic surfaces. Applications: superhydrophobic surfaces, surfactant-based therapies for lungs.

4) Transport, dispersion and mixing in multiphase turbulent flows

Keywords: turbulent jets, plumes and fountains, dispersion, turbulent mixing, stirring chemical reactors. We study the dispersion and mixing in canonical and practical turbulent flows to understand the effects of confinement, rotation, multiple phases (liquid-liquid, liquid-gas, liquid-particle). Applications: chemical reactors, oil spills, pollutant dispersion in rivers, natural ventilation.
