State of the art measurements of permanent electric dipoles (EDM) measure accumulated phase in spin-polarized gases over hundreds of seconds and are exquisitely sensitive to magnetic field inhomogeneities. The search for the neutron's EDM at Los Alamos National Laboratory (nEDM@LANL) ... En savoir plus

Gas generation and transport through porous media is a process common to many field applications such as radioactive waste and underground gas storage. In these operations, the gas phase evolution depends on the thermodynamic conditions at depth, the properties of the fluids (density, ... En savoir plus

Andra (The French National Radioactive Waste Management Agency) envisages the safe disposal of High-Level Waste (HLW) and Intermediate-Level Long-Lived Waste (IL-LLW) in deep geological storage using a multi-barrier system. To ensure the containment of radioactivity, the principle of ... En savoir plus

The era of electrical transportation is here and this includes the aviation sector. However, the electrification of airplanes is setting new challenges due to the system operating conditions and ambient conditions during flight which are highly variable. DC electrical systems are ... En savoir plus

This elaboration presents a pre-study on automatic rotor construction for the flywheel energy storage system dedicated to operate in the levitation mode. The optimization profile model is used as a basic profile source. The 3D flywheel shape is generated on the base of obtained ... En savoir plus

Crystallization phenomena are of first interest in several industrial applications (polymer forming processes, metallurgy, phase change flow, energy storage...). A classical way to model the crystallization evolution is using the Nakamura kinetics law. In this paper, a novel physics ... En savoir plus

Paddy is one of the major cereal crops cultivated in the world. For prolonged storage and usage, parboiling is one of the well-known paddy processing techniques with benefits such as improved yield, sterilization against microorganisms, insect disinfestations and retention of nutrients. ...

Lithium-ion batteries are most preferable energy storage devices for its higher energy density, flexible form factor and lightweight design than comparable battery technologies. The present simulation work is focused on incorporating contact thermal resistance within a two-dimensional ... En savoir plus

Silicon wafers represent key elements in modern microelectronics or photovoltaics. Technological fabrications of wafer sizes with large diameters (e.g. 450 mm) allow an efficient realization for integrated circuits at low cost. However, this material shows a high sensitivity to ... En savoir plus

In this study numerical simulations of moist air flow around cold cylinder are investigated. The condensation of moist air on the cold cylinder can effect the heat transfer and fluid flow around the cylinder. This physical phenomenon is encountered in a number of industrial processes ...
