Geoinspired bioreactors : from Earth's precession to stem cell production Inspired by the precession of the Earth, a new bladeless mixer has been designed, which consists of a tilted and rotating cylinder. I will first present fundamental studies on flows inside precessing cylinders. At (...)
Ce 5e épisode de « Un Zeste pour la planète » (#ZPP) est basé sur des recherches menées sur la plateforme Coriolis au sein du Laboratoire des écoulements géophysiques et industriels (LEGI, CNRS/Université Grenoble Alpes), avec la participation de : Samuel VIBOUD – CNRS - Laboratoire des écoulements (...)
Flow patterns and machine learning and to develop predictive reduced order models Modeling turbulent flows and solving the engineering problem mentioned, is a highly complex task that requires a large amount of computational resources. The alternative is developing Reduced order models (ROMs) (...)
Ultimate Rayleigh-Bénard and Taylor-Couette turbulence Rayleigh-Bénard flow - the flow in a box heated from below and cooled from above - and Taylor-Couette flow - the flow between two coaxial co- or counter-rotating cylinders - are the two paradigmatic systems in physics of fluids and many (...)
