Why is nanoscience relevant in energy? Many effects important for energy happen at the nanoscale. In solar cells, for instance, photons can free electrons from a material, which can then flow as an electric current; the ...

Les façades double-peau connaissent un développement significatif grâce à leur fonction de régulation thermique des bâtiments les protégeant des contraintes météorologiques. Par rapport aux rayonnements solaires, elles ...

Pollution in large cities is a recurring problem which governments and private companies are trying to answer. Control pollution issued by vehicles is a regularly expressed element, but this concerns the case of pollutants ...

In hot countries the use of cold is increasing for various applications: housing, food storage, ... In North Africa, the production of many perishable food is seasonal, and these foods are not available, therefore only ...

Air-conditioning, refrigeration and electricity are useful forms of energy products, usually produced using separate energy conversion technologies. Further, most end-users need at least dual energy products: typical ...

The complex multiphase flow, in a new Gas-Liquid separator, was simulated using the SST k-ω and Eulerian-Eulerian models. The flow split was imposed in the simulations using Outflow boundary condition to mimic flow control ...

L’objectif de cette étude est d’évaluer de la qualité physico-chimique des eaux lacustres appartenant aux zones humides du Park national d’El Kala situé au nord Est de l’Algérie. La qualité des eaux est assurée par le ...

In this research we study the heat transfer by turbulent natural convection of a water-copper nanofluid in a solar water heater enclosure, the heating of enclosure is achieved by the solar collector wall at constant heat ...

Dans ce travail, nous avons présenté une étude numérique de l'influence de l'angle d'incidence sur l'écoulement autour du profil NACA0012 pour différents régimes de l’écoulement (subsonique, transsonique et supersonique). Les ...

Ce travail consiste à exploiter une biomasse fongique résultante de résidus de fermentation industrielle d’un antibiotique, dans l’élimination des métaux lourds des effluents aqueux par adsorption. Pour cela, nous avons ...
