Présentation
My research primarily focuses on multiphase flow and heat transfer, encompassing a diverse range of topics within these domains. Specifically, my work has addressed subjects such as multiphase flow dynamics, phase change phenomena, and heat transfer mechanisms. For example, I have investigated diesel injection under subcritical and supercritical conditions, cavitating flows, natural convection at high Rayleigh numbers, boundary layer flow physics. Previous work at IRSN focused on the uncertainty quantification and sensitivity studies in pollutant dispersion within near-source fields. Currently, i am working on the simulation of safety in the energy field, for example the simulation of LNG, LH2 leakage, etc.
