La compagne des tests expérimentaux a été conduite sous les conditions réelles à Adrar et en période hivernale. Sa puissance standardisée est de 78.9 W et ses rendements, énergétique et éxergétique, sont également évalués. Lors du chauffage à l’ébullition de 5 litres d’eau de 11 h 30 à 14 h 30; son rendement énergétique décroît linéairement de 26.5 % à 5.3 % et son rendement éxergétique varie entre 0.38 % et 2.43 %. Comparés à d’autres cuiseurs solaires, notre prototype est efficace et ergonomique. De nouveaux indices de performance de cuiseurs solaires sont également proposés.

This paper concerns the study of a two-stage vapour absorption cycle (heat transformer and refrigerating cycle) employing the refrigerant absorbent combinations of H2O-LiBr and NH3-H2O successively. The system consists of coupling the previous absorption cycle so that the first-stage absorber produces heating water to circulate in the generator of the second stage. It is found that the system can be operated at lower hot source temperatures and, thus, it can be supplied either from flat plate collectors.

Creator An entity primarily responsible for making the resource Nouioua, Ali Dizene, Rabah Date A point or period of time associated with an event in the lifecycle of the resource 2023-10-18 Description An account of the resource L’étude d’une turbine éolienne à axe horizontal (HAWT) soumise à des conditions de fonctionnement en présence de vent est très complexe, car la machine est soumise à une variation instantanée de la vitesse et de la direction du vent, qui peut conduire inévitablement les aubes de turbine en phase de décrochage dynamique. L’intensité de ce phénomène conduit à une baisse soudaine du coefficient de portance et donc à la dégradation de ses performances aérodynamiques. Ce présent travail est une simulation numérique bidimensionnelle de la variation instantanée de la direction du vent par rapport à la pale de turbine, comparée aux données expérimentales disponibles dans la littérature. L’effet de la variation de l’angle d’incidence d’un profil S809 est donc étudié en utilisant une approche URANS pour prédire le décrochage. La modélisation de la turbulence est assurée à l’aide des modèles. Le logiciel Fluent est utilisé pour la résolution numérique des équations URANS. Les résultats numériques sont comparés aux données expérimentales rapportées par la littérature. Les résultats montrent l’importance de prendre en compte le comportement de l’écoulement instationnaire dans les analyses afin d’obtenir une estimation précise des charges aérodynamiques qui agissent sur l’éolienne.

L’objectif est d’étudier les caractéristiques des vents qui balayent le territoire et d’estimer son potentiel éolien. Pour cela, deux pylônes haubanés de 40 mètres de hauteur, équipés d’instruments météorologiques, ont été installés sur deux sites stratégiques, au Nord et au Sud. Les données recueillies, compilées avec celles de Météo France, ont permis d’étaler les résultats sur une période de dix années, admettant une bonne caractérisation.

In this study, we have improved the reaction conditions of the transesterification of the sunflower oil outcome in from frying. Fatty acid alkyl ester synthesized were characterized by the FT-IR spectroscopy and the CG-SM. For that, a range of experiences have been made in 25 °C and in 50 °C with different types of alcohols and in reaction times going from 30 to 240 minutes. The best result of fatty acid alkyl ester have been obtained at 25°C using methanol as an alcohol after an hour of reaction. Features of the obtained biodiesel under optimal conditions in particular kinematic viscosity, density, the cloud point and the flash point were determined and compared to ASTM D6751 biodiesel standards. The results show that the produced biodiesel lines with the standards and there is no major difference between EEAG and EMAG features.

The study is based on minority carrier lifetime measurements with quasi steady state photo-conductance, ‘QSSPC’. Effective minority carrier lifetime ()measured values of 12.4, 8.9, 4.9 and 3.1 are obtained respectively with four silicon surface passivation techniques: 1- Shallow phosphorous diffusion emitter (n+p), 2- Iodine-Ethanol (I-E), 3-Hydrofluoric acid (HF) emersion and 4-SiNx layer deposition. These results suggest that the shallow n+p emitter gives the eff close to the bulk lifetime due to the better surface passivation quality. Simulations made with Hornbeck-Haynes model indicate that the improvement can be correlated with the decrease of the surface recombination velocity (SRV) and the increment of bulk lifetime.
