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).

Highlights

A new theoretical framework to probe the scale/space/time transport of liquid in two-phase flows.
Morphological quantification of liquid structures using differential and integral geometry:
Strain and curvature effects on premixed flames
Turbulence theory in presence of coherent structures.
