This paper deals with the experimental study of two box-type solar cookers equipped with booster mirrors and suitable for cooking a single family’s food. The first one has a conventional, ordinary horizontal aperture area and the second one has an…

In this paper, the thermal performances of a box solar cooker were rated with F1 and F2 parameters as per Mullick’s procedure [1], the efficiency of the cooker was evaluated using energy and exergy analysis. The solar cooker was designed with an…

Partant d’un constat que, vu les faibles propriétés thermo physiques de l’air utilisé comme fluide caloporteur, les capteurs solaires à air ne donnent que des rendements médiocres. Il a été jugé très utile de disposer des obstacles "chicanes" de…

Les échanges thermiques interviennent dans de nombreux secteurs d’activités humaines. Dans la plupart de ces activités, le transfert de chaleur doit s’effectuer sans altération des milieux intervenant dans le transfert thermique. Le souci…

Une investigation numérique du comportement hydrodynamique et thermique de l’écoulement d’air dans un canal rectangulaire munie des chicanes sous forme aile est effectuée dans le présent papier. L’effet du l’insertion des chicanes a été analysé. Les…

In order to gain an understanding of the mechanism of thermal performance increase in the shell side, a shell and tube heat exchanger is proposed in this study. Numerical investigations of the shell side fluid flow and heat transfer are performed…

Senegal is one of the developing countries and its dependence upon imported fossil fuels can only be offset by the sustained exploitation of its indigenous resources. Wind energy is renewable and environment friendly, which can be harnessed for…

The sun shines on the world, but more about Algeria. From this luminous reality, exploitation and development of renewable energy such as solar and wind energy is a very important alternative to reduce gas emissions, reduce the bill for power…

Photovoltaic conversion is an optimal solution for the electrification of rural areas, especially deserts for the abundance of solar energy in these regions. In recent years, many studies have been carried out to maximize the energy productivity of a…

Nowadays, LPCVD (Low Pressure Chemical Vapor Deposition) and highly doped polycrystalline silicon films have numerous applications in microelectronic component manufacturing technologies, integrated circuits and solar cells. The complexity of the…
