Présentation
Dr. Guillaume Bois received his PhD from Grenoble Institute of Technology (Grenoble INP) in 2011. His research interests include two-phase flow modelling at the local and averaged scales, with or without phase-change. He develops and utilizes the open-source CFD code TRUST/TrioCFD for performing Direct Numerical Simulations of turbulent bubbly flows using Front-Tracking algorithm. In particular, he has studied collective effects in bubble swarms, heat transfer, and the bubble growth on a nucleation site. He has a particular interest in embedding subgrid models for heat and mass transfers in interface-resolved simulations. Besides, he is also an expert in two-phase flow modelling used in RANS two-fluid models (Neptune_CFD, TrioCFD) for which he lead a 2-years international benchmark on modelling boiling flows in high-pressure conditions with averaged approaches. He also uses the insight into turbulence and phases interactions gained from local simulations to improve and validate averaged models for momentum and turbulent transfers in industrial applications.
