Ouassim Feliachi: From particles to fluids: hydrodynamic limit and fluctuationsOuassim Feliachi (IDP-Orléans)
Thursday 25 May 2023 11:00 - IDP - Orléans: salle 016 du bâtiment physique, Tours: salle E2000
Résumé :
In this talk, I will review the main ideas and tools that allow to bridge from a particle system described through equations of motion (e.g. Newton's 2nd law), to a fluid description ruled by a hydrodynamic partial differential equation (e.g. the Navier-Stokes equations). I will also explain why in some contexts we should take into account finite particle-number effects in this process and how to do so.
