The Centre for Energy and Thermal Sciences of Lyon (CETHIL) is a joint centre between the National Institute for Applied Sciences (INSA Lyon), the French National Scientific Research Centre (CNRS) and the University Claude-Bernard Lyon 1. About 130 collaborators work for the Centre. The applications of the investigations performed at CETHIL span over a wide range of fields, including electronics, the nuclear energy sector, aerospace, the automotive industry, the design of buildings and renewable energies.
Key strengths and expertise
Research at CETHIL covers many topics linked to heat transfer and energy-related systems and devices. CETHIL is one of the key centers at the national and international levels where a so-large range of spatial and temperature scales are investigated: from the nanostructure to the building and urban area scales, from liquid helium or slurry ice up to combustion temperatures.
Topics under study can be classified according to the following categories:
- Physics of heat transport phenomena
The goal is to understand, characterize, predict or control heat transfer phenomena and their coupling to other phenomena, at different spatial, time or temperatures scales. This encompasses in particular topics involving heat convection, heat conduction, thermal radiation or phase-change heat transfer.
- Heat transfer in complex systems and devices, and their energy efficiency
Topics investigated deal in particular with building optimal energy design and devices such as refrigerators, thermal engines and combustion chambers, solar-related systems.
- Processes driven by heat transfer
The impacts of heat transfer are assessed on various types of processes, in particular for polymer shaping and industry-related application.

Following measures taken by the French Government on March 14, the Centre is physically closed from March 16 but the activity is maintained remotely. More information here.
Collaboration agreement between CNRS and the French Centre for Buildings (CSTB)
It covers research projects at CETHIL and a wide variety of scientific disciplines ranging from engineering to digital, including the humanities and social sciences.
Conference on "Climate change, how to act?" : CETHIL has some solutions
What actions should be taken to fight global warming? How can we imagine the transformation of our major energy, urban, societal systems, ? What can we do to face this great global challenge? How to mobilize individually and collectively? The purpose of this conference is to propose solutions.
How to cope with heat waves? A researcher of CETHIL answers to newspaper "Le Progrès"
Christian GHIAUS, faculty at CETHIL, reminds us that the human body is an engine that consumes energy, and that it is necessary to facilitate the dissipation of this energy towards the environment during periods of hot weather.
