الضوء حراري البرمجة الخطيةIndex. décimale : 530 Physique Résumé : The research topic formulated initially concerned the study and the development of an
optimal strategy for the operation of hybrid energy systems based on renewable energy.
To do this, we theoretically and experimentally studied some photovoltaic systems. The
procedure was the analysis of the internal and external parameters of photovoltaic cells based on the code data of the illumination measurements, the temperature over a long period. We studied the theory of wind systems and performed experiments on an experimental system developed locally.
We studied the theoretical models for the production of methane by anaerobic digesters, and carried out experiments on an experimental digester performed locally. We studied the theory of photothermal systems and conducted tests on photo-thermal developed locally.
Given the energy loss during conversion and regulation, we studied the conversion of
electrical energy from Renewable Energy systems. We conducted the study and choppers prototype simulation PWM (Pulse Width Modulation) to minimize energy conversion losses. The systems considered are nonlinear systems with more or less filter first and second order.
To reduce the cost of energy system based on a single renewable resource; we have adopted an approach of considering based on zonal characteristics and demand, the combination of two or more renewable resources that are available (solar photovoltaic, solar photo-thermal, wind power, biogas obtained by anaerobic bio reactors).
We used an optimal allocation of management resources ER model that exploits the internal and environmental characteristics. Linear programming model has been used in the case where resources are continuous and in case where these resources are discrete units, they also available.
The program is generic and can be used for any other ER resource provided to present the expression that connects the internal annual energy and environmental characteristics.Diplôme : Doctorat en sciences En ligne : ../theses/physique/BEL6875.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=10191 Elaboration d'une stratégie optimale pour l'exploitation combinée des energies renouvelables [texte imprimé] / Souad Belhour, Auteur ; Abdelouahab Zaatri, Directeur de thèse . - جامعة الإخوة منتوري قسنطينة, 2016 . - 163 f. ; 30 cm.

PhysiqueTags : physique: Physique Energétique Energies renouvelables Cheminée solaire Fluent Tridimensionnelle (3D) Turbine à gaz Renewable Energies Solar chimney Three-dimensional (3D) Gas Turbine الطاقة المتجددة مدخنة الطاقة الشمسیة Fluentثلاثي الأبعاد التوربین الغازیة Index. décimale : 530 Physique Résumé :
The solar chimney is a generator of electrical power from solar energy, based on the conversion of the kinetic energy generated by natural convection into mechanical energy. However, the efficiency of this recent technique remains low compared to other processes. In order to increase the productivity of this system, our study has examined two essential techniques that have a direct impact on the performance, the first concerns the improvement of heat transfer which is an important factor to optimize the design of the chimney solar energy and the second is related to the combination of solar energy with other systems. In order to show the effect of heat transfer, two geometrical configurations of the solar chimney were considered. A two-dimensional, dimensionless numerical study with Fluent software, as a function of Rayleigh number and for both laminar and turbulent flow regimes, was undertaken. The possibility of combining a solar chimney with a gas turbine was studied. The injection of the exhaust gas at the inlet or in the middle of the collector was examined. In addition, a three-dimensional study was conducted to show the influence of the third direction on the flow and heat transfer in both laminar and turbulent regimes. The results obtained show that the position of the wind turbine in the geometrical configuration studied has an effect on the two velocity profiles at the outlet of the collector and at the inlet of the chimney. Moreover, it is clear that the coupling of the solar chimney with a gas turbine contributes to significantly improving the efficiency. The effect of the third direction was found in purely convective regimes.

Génie ClimatiqueTags : Régions isolées energies renouvelables énergie écolienne dessalement des eaux osmose inverse récupération d'énergie Remote areas renewable energies wind power water desalination reverse osmosis energy recovery المناطق المعزولة الطاقات المتجددة طاقة الرياح تحلية المياه التناضح العكسي استرجاع الطاقة Index. décimale : 626 Génie Climatique Résumé :
Water desalination is one of the most important factors that can help in developing remote areas and the desert. A critical technical parameter of desalination applications is the way the system is powered. This decision is taken according to the selected method of desalination and the characteristics of the candidate area. Nowadays, the method of reverse osmosis dominates globally; it requires only electricity, has a quite low specific energy demand, and can cooperate with technologies of renewable energy sources such as wind turbine and photovoltaics. Hence, renewable energy-powered reverse osmosis systems are promising technologies for brackish and seawater desalination in remote regions as they exhibit low energy consumption and can be designed according to water demand and energy resource.
This study explores the feasibility of wind-desalination concepts in southern Algeria, and evaluates their economic and environmental viability. A reverse osmosis desalination system powered by a stand-alone wind turbine of 1 MW rated power and equipped with an energy recovery device is proposed to supply fresh water, from brackish water, to the rural world of three potentially high-wind sites in the southwest of Algeria, namely Adrar, Timimoun, and Tindouf. The effect of different operating and design conditions on the system performance is investigated. The paper is concluded with the economic and environmental feasibility of wind powered desalination systems for the presented case.Diplôme : Doctorat en sciences En ligne : ../theses/gclim/TRI6610.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=9728 Etudes, analyses et optimisation de la consommation énergétique des unités de dessalement pour les sites isolés [texte imprimé] / Zakaria Triki, Auteur ; Mohamed Nadjib Bouaziz, Directeur de thèse . - constantine [Algérie] : Université Constantine 1, 2014 . - 160 f. ; 30 cm.
