Summary : Heat accounts for 50% of energy consumption in Europe and is still largely produced from fossil fuels (75%). Thermal storage is a key component in the decarbonization of heat production, enabling...

Summary : In the context of the energy transition, power electronics faces several challenges in order to meet the sharp increase in electrical power transmitted. Wide bandgap semiconductor components enable the conversion of higher...

Summary : The search for technological solutions aimed at minimizing the size of a device, known as intensification, is a classic objective of process engineering. In this thesis, the intensification possibilities offered by helical tubes are studied, both...

Summary : Carbon dioxide (CO₂, R744) is a promising alternative for refrigeration systems because it does not contribute to ozone depletion and has very little impact on global warming compared to...

Summary : Efficient heat exchanger design is crucial for cost, sustainability, and energy conservation. Due to its importance, the research interest in optimal HX design has increased across various industries, especially in the aerospace sector. Here, compact heat exchangers with…

Summary: Since the industrial revolution, the evaporation of water has been the most common method for providing industrially usable energy. As of today, important primary energy sources for the evaporation are limited and globally unevenly distributed fossil fuels, whose combustion…

En cette rentrée de septembre 2025, le GRETh est heureux d’annoncer l’arrivée de 3 nouveaux membres au sein de l’association ! AIREDIF est une entreprise française fabricante et distributrice d’échangeurs de chaleur proposant notamment des Batteries de Tubes à Ailettes,…
