Fluid Mechanics - Energetics

Fluid Mechanics – Energetics

The activities of the department are grouped around Fluid Mechanics, Mass and Heat Transfer and Energetics. We conduct research of a generally fundamental nature, with applications in the energy, transport, health and environment sectors.

Approach and perspective

The approach of the Mechanics-Energetics department is at the interface between computer science, physics and applied mathematics.

We wish to maintain a balance between interdependent activities:

  • understanding the fundamental phenomena of turbulent fluid mechanics,
  • tackling complex multiphysics problems coupled at large scales,
  • leveraging our physical knowledge while considering data as an inherent part of modeling, experiments and simulations.

In this context, we are very open to recent developments in machine learning, which offer a powerful information processing framework that can augment our current lines of research with broad-spectrum applications in the energy, transportation, health, and environmental sectors.

Organization

The Mechanics-Energetics Department offers original and multidisciplinary research thanks to the expertise of some twenty permanent staff, researchers, teacher-researchers and engineers, organized into two complementary teams: DATAFLOT (DAta science, TrAnsition, FLuid instabiLity, contrOl & Turbulence) relying on data-augmented modeling and artificial intelligence, and studying fluid dynamics, instabilities and turbulence, and COMET (COuplages MultiphysiquEs et Transferts) focusing on the understanding of complex coupled fluid phenomena, involved in energy conversion and storage, heat transfers as well as energy efficiency optimization.
