Webinar Sébastien Galtier

Heat and mass transport in porous media: Insights from experiments, simulations, and modelling.

Sébastien Galtier obtained a PhD at Observatoire de Nice in 1998 under the supervision of Prof. Annick Pouquet. His PhD was on 'MHD turbulence and intermittency'. He joined the Mathematics Institute of University of Warwick in 1999 as a post-doc before to obtain a permanent position at University Paris-Sud in 2001. He is now Professor in Astrophysics at Université Paris Saclay in the "Laboratoire de Physique des Plasmas". He was awarded as Junior and Senior member of Institut universitaire de France (IUF). His research interest is on turbulence in astrophysics and cosmology. He uses both high level mathematical tools and massive numerical simulations to study the properties of turbulence and discover new fundamental laws. The domains of application are diverse: solar wind plasma, supersonic interstellar medium, solar coronal heating, dynamo in stars and planets, and primordial gravitational waves. Magnetohydrodynamics (MHD) and general relativity are the main equations used to investigate these questions.

Webinar Rodney O. Fox

Simulation of the Grenoble bubble-column experiment

Prof. Rodney O. Fox joined Iowa State University in 1998 as the Glenn Murphy Professor of Engineering, later becoming the Herbert L. Stiles Professor of Chemical Engineering until 2012. He is been an Associate Scientist at the US-DOE Ames Laboratory since 2001, rising to Distinguished Professor in 2010. Prof. Fox held visiting professorships in Belgium, Denmark, France, Italy, Switzerland, and The Netherlands, and was a NATO Postdoctoral Fellow in France from 1987 to 1988. Among his awards are a NSF Presidential Young Investigator Award in 1992 and ISU Outstanding Achievement in Research Award in 2007. He was elected Fellow of the American Physical Society in 2007 and the AIChE in 2020. Prof. Fox received the North American Mixing Forum Award for Excellence and Shell Particle Technology Forum Thomas Baron Award in 2016. In 2022, he was named the Fulbright-Tocqueville Distinguished Chair and Jean D’Alembert Senior Chair at the University of Paris-Saclay, CentraleSupélec. Prof. Fox’s contributions to multiphase and reactive flow modeling are groundbreaking. His group developed novel computational fluid dynamics models, including powerful quadrature-based moment methods (CQMOM, GQMOM, HyQMOM). His research spans turbulent flow, chemical reactions, and multifluid models. His books, Computational Models for Turbulent Reacting Flows (2003) and Computational Models for Polydisperse Particulate and Multiphase Systems (2013), are authoritative works in the field.

Webinar Paolo Errante

Liquid spray injection in a CO2 High Voltage Circuit Breaker

Paolo Errante obtained a Ph.D. in fluid Mechanics at the LMFA of the Ecole Centrale de Lyon in 2020, the major contribution involved developing an innovative interpolation method, ensuring thermodynamic consistency in multi-phase and multi-species flows. In between these activities Paolo also have explored non-intrustive uncertainty quantification technique to better understand and calibrate lagrangian evaporative sprays. Following he pursued with a two-year post-doctoral position at LMFA, where he focused on studying the challenging DNS of supersonic turbulent channel flow of dense gases. This simulation helped to identifying sub-grid scale terms to be modeled, in the context of dense gases. The data produced are made available to develop AI models for CFD. At the end of this project, Paolo embarked on a one-year post-doctoral venture in Cambridge, where its work was more oriented to combustion modeling. During this period he constructed an algorithm for the Flamelet Generate Manifold modeling approach, implemented in the NEWT code. Nowadays Paolo Errante works at LMFL-L2EP as a research Engineer, mainly focused on coupling Data-Assimilation techniques with numerical models.
