THEME DE RECHERCHE

Le thème de recherche que je développe se concentre sur la modélisation et la simulation numérique multi-échelles des écoulements à phase dispersée (bulles, gouttes et particules solides). En plus de l’hydrodynamique couplée du fluide et des inclusions, je m’intéresse à la simulation numérique de milieux réactifs diphasiques (verre fondu peuplé en microbulles, suspensions denses en cours de polymérisation) et des suspensions où les effets non-hydrodynamiques ne peuvent plus être négligés (particules magnétiques, interactions de surface, suspensions biologiques).
