Innovation of the energy saving and optimization of the renewable sources are the most important sides of the building sector in the last years. Considering that buildings consume more than 40% of all the energy we use and about 50% of it is used for the c ...
Time lag and quantization in temperature sensors in enterprise servers lead to stability concerns on existing variable fan speed control schemes. Stability challenges become further aggravated when multiple local controllers are running together with the f ...
In this study, we report the morphological and structural properties of amorphous and nanocrystalline Si thin films deposited by inductively coupled plasma-assisted chemical vapor deposition (ICP-CVD) technique at low substrate temperatures using H-2 dilut ...
An important challenge for the next generation of high performance datacenters is to guarantee sufficient, reliable, green and cheap cooling of the server blades. Since this seems unrealistic with air cooling technologies due to the expected ever higher ch ...
Gas turbine operation at elevated temperatures ensures increased thermal efficiency and useful power output. However, the industrial tendency to push further firing temperatures is limited by the capabilities of the current turbine blade cooling technologi ...
In this work, we studied the thermal behavior of mono or multilayer walls of various compositions consisting of traditional and modern building materials, in order to identify those that provide good comfort and better energy conservation in conditioning c ...
Francis turbines operating at part load condition experience the development of a cavitating helical vortex rope in the draft tube cone at the runner outlet. The precession movement of this vortex rope induces local convective pressure fluctuations and a s ...
Suitable developments of sustainable energy sources are drawn by analysing the Energy sector, considering environmental, economic and social aspects. The particular example of Switzerland is detailed with a focus on the energy consumption in the buildings. ...
The development of an efficient isothermal turbine and compressor is essential for the realization of a small-scale compressed air energy storage (CAES). This article presents the theoretical development of an oil-free co-rotating scroll air compressor and ...
