Le rôle des turbines à gaz, dans la production d’électricité, de l’industrie pétrolière et dans les réacteurs à neutrons rapides refroidis en utilisant l’hélium comme fluide caloporteur a pris une attention particulière ces dernières années. A cet effet, différentes méthodes (régénération, refroidissement intermédiaire, préchauffage et injection de la vapeur d’eau) ont été utilisées afin d’améliorer les performances des cycles de turbines à gaz. Dans cette optique, la méthode d’injection de la vapeur d’eau à l’amont de la chambre de combustion d’une turbine à gaz a été proposée, étudiée et comparée avec un cycle simple. L’objectif principal de ce travail consiste à la réalisation d’un programme de calcul de l’influence des conditions ambiantes sur les caractéristiques des différents composants de la turbine à gaz, telles que la compression, la combustion et la détente. Une fois que les paramètres de fonctionnement optimaux sont connus, le recalcul des performances de l’installation a été effectué en injectant des quantités convenables de vapeur d’eau à l’amont de la chambre de combustion. Les résultats obtenus de l’influence des conditions ambiantes sur les performances de la turbine à gaz sans injection de la vapeur d’eau et l’influence des conditions standards sur le début d’injection, selon ceux trouvés dans la littérature simulés par le code de calcul thermodynamique ‘Thermoptim’, sont en bonne concordance avec la variation qualitative de ces conditions, dans le cas d’un fonctionnement normal sans injection de la vapeur. Ces résultats sont représentés sous forme de courbes en deux et à trois dimensions pour une meilleure illustration des phénomènes physiques.

Cet article présente le travail de mise au point d’un régulateur de charge/décharge pour une batterie au plomb 24 V installée dans un système photovoltaïque de faible puissance. Ce régulateur, piloté par un microcontrôleur ST62E25, permet la protection de la batterie contre les phénomènes de surcharge, de décharge profonde, et les dérives de températures à l’aide d’un algorithme qui compare la tension de batterie à des seuils compensés en température ou en courant. Une nouvelle méthode pour le calcul du seuil de limitation de décharge a été proposée. Outre la fonction de protection, ce régulateur permet aussi d’afficher numériquement les grandeurs utiles du système et communiquer ses données à l’ordinateur via une liaison RS232. Des résultats expérimentaux ont été aussi présentés pour illustrer le fonctionnement du régulateur de charge/décharge proposé.

Dans ce travail, nous avons utilisé un nouveau floculant organique biodégradable extrait de jus de cactus (figuiers de barbarie, voir photo ci-dessous), dans un procédé physico-chimique (coagulation floculation) afin de traiter des rejets liquides chargés en chrome (VI). Ce bio floculant nous a permis de réduire la turbidité d’un effluent industriel, en passant de 100 NTU à des valeurs au dessous de 2 NTU. L’étude a été réalisée sur des échantillons pseudo industriels préparés au laboratoire et des échantillons industriels issus d’une unité de traitement de surface (chromage). L’étude comparative entres le floculant organique et le floculant industriel PPRQESTOLR 2515.TR (floculant à base d’acrylamide et acrylate de sodium), a montré que notre bio floculant aboutit à des résultats satisfaisants au niveau du pouvoir de floculation. Une neutralisation et coagulation avec la chaux, suivi par une floculation, puis une décantation, pour la solution du chrome (VI) réduit en chrome (III) a montré un effet très significatif sur l’abattement de la turbidité et un pourcentage de rétention de chrome (VI) de plus de 99,5 %. Les résultats obtenus sont très encourageants et incitent notre équipe de recherche à développer cet axe de recherche afin de mettre en place des procédés alternatifs propres pour le traitement des eaux d’une manière générale et qui en même temps permettent la valorisation des ressources naturelles nationales.

Contrairement aux réserves en combustible fossile, la quantité d’énergie disponible varie avec la saison et l’heure du jour. L’énergie éolienne est davantage influencée par la topographie que l’énergie solaire. De plus, la quantité totale d’énergie éolienne convertible sur le territoire d’une nation, dépend de façon significative des caractéristiques, du rendement espéré, du dimensionnement et de la répartition horizontale des éoliennes. Nous avons présenté dans ce travail, dans une première partie une modélisation et une simulation d’un système de conversion éolienne et donc une estimation du potentiel énergétique éolienne (puissances disponible, récupérable et utile) sur des sites Algériens (régions sahariens: Tindouf, In Salah et In Amenas) et dans une deuxième partie une présentation d’un système de pompage éolien par des aérogénérateurs des caractéristiques différentes (Puissance nominale PN , vitesse de démarrage VD , vitesse nominale VN et la vitesse d’arrêt de la machine VM ).

Cette optimisation peut être obtenue par augmentation de la surface d’échange par introduction des obstacles de formes géométriques différentes. Pour cela, nous avons garni la veine d’écoulement d’air par plusieurs rangées d’obstacles de formes cylindriques placées perpendiculairement à l’écoulement. Ces obstacles sont assimilés à des rugosités artificielles dites chicanes. Le travail consiste à déterminer les performances thermiques et dynamiques de la configuration proposée par la méthode pas à pas tout en utilisant les corrélations de Zukauskas concernant le nombre de Nusselt et le régime d’écoulement.

It has many advantages, notably when it is associated with a PV system. Indeed, the autonomous hybrid system presents the advantage of the important power supplied with reduced number of converters. The objective of this work presents a general study of the fuel cell system. The most components of this system are: the converter DC-DC booster –Converter DC-AC PWM– transformer and the isolated load. The different elements of the Fuel cell system are dimensioned to conceive a general model simulated with Matlab / Simulink. The obtained results show the validity and the efficiency of the model presented.

The blocks are equally spaced and heated by a uniform volumetric heat generation. The objective of the study is the determination of the enhanced cooling of the blocks when the channel is filled with a porous medium. The problem is modelled by the continuity, momenta and energy equations with their appropriate initial and boundary conditions. When the channel is filled with a porous medium, a Darcy-Forchheimer-Brinkman flow model is used to describe the flow field. The model equations are numerically solved by a second order accurate finite volume method. The results show that the flow field of the channel filled with a porous medium is very different from that of the channel without the porous matter. A major difference is the appearance of circulating vortices between the blocks when the porous matter is inexistent. This flow pattern difference favours a convective heat transfer enhancement of the flow in the channel filled with the porous matter. Moreover, the effective thermal conductivity of the considered porous medium is higher than that of the fluid. These two factors lead to a considerably better cooling of the blocks mounted in the channel filled with the porous matter. Thus, the use of porous media when possible is recommended because it enhances the cooling of heated blocks mounted in channels.
