GAB, modified Halsey and Peleg models were fitted to the experimental data and the agreement between experimental and predicted values was satisfactory. Calculation of the thermodynamic properties was further used to provide an understanding of the properties of water and energy requirements associated with the sorption behaviour. Isosteric heats of sorption were calculated through direct use of moisture isotherms by applying the Clausius-Clapeyron equation. The differential enthalpy and entropy decreased with increasing moisture content and were adequately characterized by a power law equation. A plot of differential heat versus entropy satisfied the enthalpy-entropy compensation theory.

La mise en oeuvre d’une méthodologie de conception fondée sur la modélisation multi physique est l’objet de cet article. Elle consiste à associer une approche analytique et une approche numérique utilisant la Méthode des Eléments Finis (MEF). Un outil logiciel est alors réalisé par le couplage d’un outil logiciel commercial d’aide à la conception des systèmes modélisables analytiquement à des codes de calcul par la méthode des éléments finis développés par Cedrat et nommé Flux 2D. L’étude analytique, fondée sur un modèle magnétoélectrique, fournit une solution qui répond globalement aux spécifications d’un cahier des charges bien déterminé. L’analyse numérique complète, d’une part et le dimensionnement en intervenant sur un nombre réduit de paramètres géométriques, d’autre part, permet d’étudier le comportement vibratoire du dispositif dimensionné en utilisant un modèle magnéto mécanique.

Les avantages de combiner un collecteur thermique et un module PV dans un seul capteur sont l’augmentation de l’efficacité totale de la conversion d’énergie solaire et l’uniformité architecturale dans le cas d’utilisation sur un toit. Les coûts seraient également réduits, comparés aux deux systèmes (photovoltaïque et thermique) séparément installés. Nous présenterons dans cet article, une étude de simulation numérique sur le comportement thermique des capteurs hybrides à travers l’élaboration de la cartographie thermique du capteur hybride photovoltaïque thermique. La combinaison d’un capteur thermique et d’un panneau photovoltaïque dans un seul capteur permet l’augmentation de l’efficacité de la conversion totale de l’énergie solaire. Un effet de synergie peut être obtenu dans une structure associant ces deux dispositifs de façon judicieuse à ceux du système photovoltaïque et thermique séparément installés. Les résultats obtenus permettent de dire que le panneau photovoltaïque est un générateur d’énergie calorifique qui peut être exploité pour chauffer de l’eau, ou pour préchauffer l’espace, ou bien encore l’associer avec une pompe à chaleur pour la climatisation.

Néanmoins, l’accès à ces sites étant généralement long et difficile, les coûts de maintenance et d’approvisionnement en carburant sont très élevés. En conséquence, nous avons envisagé de coupler -au sein d’un système hybride- un générateur diesel avec deux sources d’énergies renouvelables (éolien - photovoltaïque) qui représente alors souvent l’option la plus économique. Cependant, notre étude porte sur l’alimentation d’une habitation, qui peut être située sur différents sites algériens, par le système hybride avec stockage électrochimique. Dans un premier temps, nous nous sommes basés sur la modélisation détaillée des composantes du système, puis sur l’ensemble du système. Ainsi, nous avons appliqué les modèles et dimensionner le système, ce qui nous a permis d’aboutir aux meilleurs performances. Enfin une étude économique a été élaborée afin de comparer les contraintes financières que présente chacun des systèmes étudiés.

Nous proposons l’amélioration du fonctionnement d’un système photovoltaïque suite aux brusques variations des conditions météorologiques et la charge. Ceci est obtenu par l’association d’un circuit de détection de dysfonctionnement et de changement de sens ‘CDCS’ conçu au cours de ce travail. Le rôle de ce circuit ‘CDCS’ est de détecter un éventuel dysfonctionnement du système ‘PV’ puis converger le système vers les conditions optimales sans redémarrer le système photovoltaïque.

Those performances such PV efficiency, inverter efficiency and flow rate are improved by a judicious control implanted on the converters. The maximal power point tracking (MPPT) control allows the extraction of the maximum output power delivered by the PV generator. However the inverter insures a pulse width modulation (PWM) control of the asynchronous motor and a sine wave form of output signals. We proceed to modelling the PV pumping system with power electronic converters allowing respectively optimal operating point tracking and power conversion under the appropriate command. From the obtained simulation results, under Matlab/Simulink environment, we will discuss how the ambient temperature and the solar radiation influence the performance of the PV plants. The experimental results of the PV pumping system installed in Tunisia (2.1 kWc) verify the validity of the model and the proposed controller.

The theoretical determination of the heat transfer phenomena which occur in the system was used to elaborate a numerical model, needed for a parametric evaluation of the system. The parametric study identified the parameters which have the higher influence on the system efficiency and allowed us to quantify the contribution of each of them. We can notice that for the climatic data, the cold water input temperature as well as the ambient temperature showed a major effect on the warm water output. For the construction characteristics, the most influencing factors are the transmissivity of the glazing and the painting of the tank.

Ce travail se propose de contribuer à l’optimisation d’un séchoir solaire polyvalent pour plantes aromatiques et médicinales, en déterminant expérimentalement la courbe caractéristique de séchage convectif des feuilles de marjolaine. La cinétique de séchage est étudiée pour trois températures (40, 50 et 60 °C) et pour deux débits d’air asséchant (0,028 et 0,056 m3.s-1). L’augmentation de la température dans le milieu a réduit de manière significative le temps de séchage. Les données de séchage de ce produit ont été analysées pour obtenir les valeurs de la diffusivité effective lors de la période de séchage à allure décroissante. Dans cette période, le transfert d’humidité à partir des feuilles de marjolaine a été décrit en appliquant le modèle diffusif de Fick. La diffusivité effective a varié entre 7,19 10-12 et 1,17 10-10 m2.s-1 avec l’augmentation de la température du milieu. La relation d’Arrhénius avec une valeur d'énergie d’activation moyenne de 82 kJ.mol-1 a exprimé l’effet de la température sur la diffusivité effective. La vitesse de séchage est déterminée empiriquement à partir de la courbe caractéristique de séchage. Sept modèles mathématiques ont été utilisés pour la description des courbes de séchage. Le modèle mathématique ‘Logarithmique’ semble le plus adéquat pour décrire les courbes de séchage des feuilles de marjolaine avec un coefficient de corrélation r voisin de l’unité et dans des conditions aérothermiques contrôlées.
