With around forty members (teachers, researchers, engineers and PhD students)the THERMIE team carries out research activities on energy  conversion systems  (thermal driving and receiving machines, exchangers), the energy of multi-source systems. energy, building energy and on complex flows through experimentation (optical, spectroscopic, IR, intrusive metrology) and digital simulation.


The research work of the THERMIE team revolves around five disciplinary scientific poles and two transversal scientific poles with the SHARPAC team:

Disciplinary scientific poles :

- Fluidic and thermal metrology and instrumentation: develop specific diagnostic and instrumentation methods (optical or based on thermoelectric effects), non-destructive methods for determining the properties of construction materials and magnetocaloric materials. - carry out measurements of thermo-fluidic quantities by innovative methods

- Thermal energy systems: develop multiphysics modeling tools in wide fields of application (thermal / electrical / magnetic / fluid coupling).

- Thermal machines: design and characterize machines with external heat input, refrigeration machines, heat pumps.

- Complex flows: study the instabilities and turbulence linked to complex flows (alternating, supersonic, inhomogeneous) and the associated heat transfers (fluid / wall, porous matrices)

- Building energetics: resorting to interdisciplinarity between engineering sciences (building thermal) and human sciences (history and heritage sciences) to try to have the most exhaustive possible approach of the properties of old buildings.

  - Magnetocaloric devices: study and characterize magnetocaloric materials. Develop magnetocaloric heat pumps.

Transversal scientific poles:

- Cogeneration: design and characterize cogeneration systems. Recover industrial waste for the production of electricity or mechanical energy.
