The purpose of these meetings is to promote cooperation between the scientific teams of the participating countries and to give young researchers the opportunity to present their work. They focus on energy and more particularly thermal and renewable energies. French-speaking at the beginning, because stemming from the scientific cooperation between France and the three Maghreb countries, these JITH days strive to open up and become more and more international.
The JITH days as bi-annual event bring together on average 150 to 200 participants, their profiles being either permanent staff or PhD students from diverse laboratories working on JITH themes in the three Maghreb countries and in France. Other countries regularly participate (Madagascar, Cameroon, Senegal, Germany, Canada, Spain, Romania, etc.).
The main scope of JITH was originally heliothermal (the TH of the JITH acronym meant Hehiothermic Transfers). This scope then evolved and was extended to energetics and more particularly thermal (the TH today meaning Thermal) and its applications. Thus, for three or four editions, the JITH days have been divided into three permanent topics and a specific topic for each edition:
- Fundamental developments in the fields of energy and environment
- renewable energy
- Thermal machines and mass and heat transfers in industry, construction, agriculture and transport
- Specific theme (2015: Fire, 2017: Thermal Storage and Conversion, 2022: Hybrid Energy Systems)
During the JITH days held in Marseille in October 2015, new orientations concerning energy and the environment found a very favorable response within the JITH community, which is encouraging to strengthen this approach in the future.
