The Solargeotherm project is assessing the possibility of using vertical geothermal probes drilled into a rock mass (bedrock) for storing the thermal energy produced by solar panels and later releasing it. The research project relies on the installation of an experimental system and the ... En savoir plus

PEM Fuel Cells’ durability and performance can be increased using an ejector based hydrogen recirculation system. In this work, a CFD model has been implemented to simulate the flow within an ejector used to recirculate hydrogen in PEM Fuel Cell systems. The model has been validated ... En savoir plus

The storage of hydrogen as an absorbed element in metal hydride bottles is a promising technique for energy storage. In this work, a three-dimensional model of a charging process in a metal hydride container has been developed to simulate the absorption reaction and resultant heat and ... En savoir plus

Continuous heat treatment is employed in food industry as a key step in the production of selected products, like dairy desserts. The evolution of an aqueous suspension of starch granules along an existing heat exchanger is here studied by 3D modeling of fluid flow, heat transfer and ... En savoir plus

Earth heat exchangers are drawing increasing attention and popularity due to their efficiency, sustainability and universality. In addition, DBHE can offer higher temperatures and more return on investment than conventional system. DBHE is also an alternative to geothermal power ... En savoir plus

In magnetically confined fusion devices, electron cyclotron resonance heating (80-170 GHz) is characterized by a local RF-power deposition at the electron cyclotron resonance [1]. A mm-wave RF Gaussian beam is launched from a dedicated antenna and propagates through the highly turbulent ... En savoir plus

The high power of X-ray beam delivered by synchrotrons and free electron lasers, up to 240 W/mm2, requires heat load management solutions to obtain the best performance from the optical elements which will shape the beam for its use in the experimental stations [1]. One solution is the ... En savoir plus

We present studies of the electric field configuration that guides the electrons to the strips through the mesh and its importance to the detector’s optimal operation. Furthermore, analysis of the gas propagation inside the chamber for different gas distribution schemes is discussed. All ... En savoir plus

The "Lithic Hypar" research is based on the mechanical analysis of an innovative reinforced stone's structure, architecturally designed by Prof. Fallacara, University of Bari (Italy): the headquarters entrance portal of the French company SNBR (Société Nouvelle Batiment Régional) located ...

In the nuclear fuel cycle, fluorine is produced by the electrolysis of the molten salt KF-2HF. It is a complex process to study since hydrofluoric acid and fluorine are hazardous and highly corrosive. A 3D-model of a lab-scale fluorine electrolysis cell has been developed to increase ...
