The Bridgman process is used in the production of single crystal superalloys for use in high temperature applications. The mechanical properties of these superalloys are strongly influenced by the microstructure that is formed during the solidification. The formation of the ... En savoir plus
The modelling of the optical and thermal response of translucent composite materials submitted to a high-energy laser irradiation is very complex, as glass fibers-reinforced polymers are highly heat-sensitive and their physical behavior dramatically changes at high temperatures. All ... En savoir plus
The activity focuses on improving the overall performance and design of a small-sized heat exchanger. This heat exchanger is designed to raise the temperature of a fluid (water), using tubular electric heaters. The device consists of a steel case with two hydraulic connections for fluid ...

In the development of advanced welding torches, a significant challenge lies in optimizing design and performance while minimizing costs and environmental impact. Traditionally, this has involved extensive physical testing, which is both time-consuming and resource-intensive. To address ... En savoir plus
Present work is done in the framework of the SisAl Pilot EU project, which aims at optimising the silicon production in Europe by recycling materials and using a carbon-emission friendly technology. The silicon production experiments are conducted on laboratory and pilot scales in ... En savoir plus
Corals are symbiotic marine organisms greatly dependent on the dynamic gradients of light, temperature and chemical species, all affected by the water flow in their surroundings. We developed a multiphysics modelling approach to simulate the microscale spatial distribution of light, ... En savoir plus
1 Problem Description Most studies for investigating heat and mass transfer phenomena in sorption storage systems use 1D or 2D numerical models. These are inadequate for analyzing processes in more complex geometries used in current prototypes. We present here a 3D model for the ... En savoir plus
In the nuclear industry, and particularly at Framatome, mastery of welding processes is essential. Framatome is one of the world leaders in this field and wants to improve even more. The work presented focuses on improving the TIG (Tungsten Inert Gas) welding process, and more ... En savoir plus
Refrigeration plays a crucial role in both industrial and residential sectors, where nearly 17% of the energy consumption worldwide is related to thermal management systems [1] [2]. Furthermore, current vapor-compression refrigeration technology contributes significantly to the ... En savoir plus
