Julien Chauchat Je suis Directeur de Recherche à INRAE et membre de l'Institut des Géosciences de l'Environnement (IGE).

Présentation

Mes activités de recherche se concentrent sur les processus de transport de sédiments à fine échelle, allant des mécanismes physiques fondamentaux tels que les interactions particule-particule ou les interactions particule-turbulence à la recherche appliquée telle que l'affouillement autour des structures hydrauliques. Mon objectif est d'améliorer notre compréhension des processus physiques en utilisant des expériences de laboratoire et des approches de modélisation en mécanique des fluides afin d'améliorer les capacités prédictives des modèles d'ingénierie. Pour atteindre cet objectif, je collabore avec différentes institutions de recherche nationales et internationales de haut niveau (Université du Delaware, Penn State University, Karlshruhe Institute of Technology, Université de Manchester, Aix-Marseille University, Université de Rennes, INRAE Grenoble). Nous avons publié une version open-source d'une nouvelle génération de modèle de transport de sédiments : sedFOAM qui vise à fédérer l'effort de recherche autour de ce sujet.

En 2021, ARTELIA GROUP (société internationale de conseil en ingénierie), a financé la chaire industrielle OXALIA pour favoriser l'émergence de nouvelles approches de modélisation pour les applications d'ingénierie. Je suis actuellement titulaire de cette chaire.
