Webinar Marc Medale

When does gravity actually influence the macroscopic contact angle in partial wetting problems?

Marc Medale has his expertise in numerical modeling of coupled heat and fluid flows, with particular emphasis on natural and mixed convection fluid flows with or without phase change along with partial wetting problems. The developed models address both Newtonian and visco-plastic rheologies and they aim at computing branches of steady state solutions, detect bifurcation points if any, by means of continuation algorithms based on the Asymptotic Numerical Method and finally perform linear stability analyses when relevant.

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.
