In metallurgy, the use of numerical models is popular because of the many coupled physical phenomena that occur during the various processes. For instance, the resulting shape and metallurgical state of a material are very sensitive to changes in temperature. The drop in temperature of ... En savoir plus
The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... En savoir plus
Pumped two-phase cooling for improving thermal management of IGBT in rail transportation has been investigated both experimentally and numerically. The experimental study on pumped two-phase cold plate of IGBT used in HXD1C locomotives was conducted at a mass flow rate of 0.1 kg/s to 0 ... En savoir plus
Transforming the energy sector worldwide towards renewable, climate-neutral energy sources requires innovative ideas and excellent engineering solutions. In particular, shallow geothermal energy utilization is currently showing a remarkable development. In highly urbanized regions, large ... En savoir plus
In order to reduce the environmental footprint of a serial production of head lamps, one lever is to replace and employ new materials, often requiring to redesign the product to ensure its mechanical and thermal resistance. In this context, this paper studies the modelling of the heat ... En savoir plus
