Research

My research interests lie in the field of fluid mechanics with special emphasis on

Fluid turbulence,
Scalar turbulence,
Premixed flames,
Multiphase flows.

Such flows unveil a wide and continuous range of scales and are further influenced by a wide variety of physical parameters. Chacterizing this multi-scale, multi-dimensional phenomenon thus requires some specific tools, some of which remain yet to be elaborated. More recently, I have focused on liquid/gas flows. I work in the “Atomization and Spray" group in close collaboration with J.-B. Blaisot, C. Dumouchel, M.-C. Renoult, T. Ménard, B. Duret and F.-X. Demoulin.

I tackle such phenomena using

a “Bottom-Up" approach from the study of elementary processes (ligament atomization, deformation of a single drop), to more complex flows (turbulent, anisotropic, inhomogeneous, in presence velocity shear).
For each situation, a “Top-Down" theoretical framework is elaborated, on the basis of exact deterministic equations, to simplified equations (averaged) down to scaling laws for modelling purposes.
Theory is then tested/upgraded using either experimental (quantitative vizualisation techniques) or numerical data (ARCHER).
