Thermics, flows, instrumentation and energy efficiency


Composed about thirty professors, researchers, engineers and PhD students, the THERMIE team conducts research activities on energy  conversion systems, the energy of multi-source systems. energy, building energy and on complex flows through experimentation and numerical simulation.


The research work of the THERMIE is based on three scientific axes :

Disciplinary scientific poles :

  • Energy and buildings (BAT) – Facilitators: Yacine AIT OUMEZIANE, Sylvie BEGOT. The work carried out within the framework of the BAT axis aims to assess and improve the hygrothermal, energy and environmental performance of a building, in order to meet energy needs with a view to reducing greenhouse gases emissions. To do this, skills and know-how enable studying material and heat transfer in porous environments and alternative energy systems for buildings.
  •  Machines and thermal systems (MACS) – Facilitators: Philippe BAUCOUR, François LANZETTA. Firstly, MACS is working on the design and characterization of external heat supply machines, refrigeration machines or heat pumps. Research also concerns the study and optimization of active regenerative magnetic cycles. Finally, activities focus on the development of innovative methods for modeling and simulating the thermo-electric behavior of complex systems with industrial applications (vehicle electrical harness, pantograph-catenary, batteries or power transformers).
  • Metrology and instrumentation for energy (METRO) Facilitators: Dimitri BONNET, David RAMEL The METRO axis is based on a strong experience in optical metrology, thermoelectric effects and the modeling of associated physical phenomena to develop specific diagnostic and instrumentation methods for energetics. This know-how makes it possible to control the entire measurement chain (instrumentation, modelling, data processing) in order to propose new methods that meet current challenges (specific environments, coupling of measurements, spatio-temporal resolutions).
