My research activities focus on the modeling and simulation of multiphase flows in chemical engineering and energy processes such as gas-liquid flows, with a specific interest on their coupling with heat and mass transfer (e.g. gas purification, hydrogen production) and with phase change (evaporation, boiling).

I address these phenomena through a multiscale approach. At the smallest scale, interface-resolved simulations (Direct Numerical Simulations) of single bubbles / droplets give access to the local mechanisms governing interface dynamics and transfers between phases. These results support the development of closure laws, based on analytical or semi-empirical approaches, for interfacial transfer and wall interactions (e.g. boiling heat transfer). The closure laws are then implemented in Euler–Euler models (Reynolds-Averaged Navier Stokes, Large Eddy Simulation) to simulate flows at the scale of process equipment, and validated against experimental measurements.

This work relies on HPC simulations that I setup both as a user and developer of several CFD codes, including neptune_cfd, code_saturne, DIVA and OpenFOAM. These developments are conducted in close collaboration with partners such as IMFT, CEREA and EDF R&D.
