Optimisation d’un système hybride de production d’énergie pour site isolé: cas de la ville de Ngaoundéré

Ce travail, présente l’optimisation d’un système éolien-photovoltaïque-micro-turbine à gaz avec batterie pour l’électrification des populations n’ayant pas accès au réseau électrique. Les résultats de simulation montrent que l’insertion de la…

Optimization of osmotic dehydration of tomatoes slices in salt and sucrose solutions using response surface methodology

Response Surface Methodology (RSM) was used to investigate the effect of temperature solution, immersion time, salt concentration and sucrose concentration on the water loss and solid gain during osmotic dehydration of tomatoes slices. The optimum…

Theoretical and numerical approaches of a plane, laminar and non-confined, impinging jet

We propose in this paper, a numerical study of a planar impacting jet flow. The flow is assumed isothermal, laminar and unconfined. The developed computer code is based on the finite volume method, which was used to discretize the N-S equations. The…

Simulation de l’écoulement autour d’un profil à l’aide d’une méthode DES

Ce travail concerne l’étude du comportement d’un écoulement turbulent autour d’un profil d’aile NACA23012. Nous avons effectué des simulations numériques de l’écoulement. Elle est réalisée par le logiciel CFD qui est basé sur la méthode de volumes…

Preparation of activated carbon based on synthetic and agricultural wastes: application to the adsorption of methyl orange

This study focus on the optimization of operating conditions for activated carbons preparation starting from synthetic waste (tires) and agricultural waste (date pits) by chemical activation. The experimental design was used in order to determinate…

Techno-economic feasibility study for the use of photovoltaic energy on the south-east algerian farms

This works aims to study the technological feasibility and economic viability of standalone Photovoltaic system for the electrification of farms in the south-east of Algeria. The PV system power plant is sized to supply potato farm in Akfadou-El…

Structural, electronic, optical and elastic properties of Mg3TH7 (T=Mn, Tc and Re) complex hydrides: First-principles calculations

The structural, electronic, optical and elastic properties of Mg3TH7 (T=Mn, Tc, Re) complex hydrides have been investigated by using the density functional theory ‘DFT’ within the generalized gradient approximation ‘GGA’ parameterized by the Perdew,…

Numerical study of mixed convection flows in a U-shaped channel

In this work, we study numerically mixed convection flows in an open U-shaped channel. The right opening lets pass fresh air at cold temperature TC, while the walls of the channel are heated at the temperature TH > TC. Our study is based on a…

Modeling and control of active and reactive powers of wind energy conversion system in variable speed based on DFIG

This article describes the modeling and control of wind conversion chain system based on DFIG in variable speed. In fact, the aerodynamic and the electrical models of the wind conversion chain are presented and discussed. Also, the adjustment of…

Etude expérimentale du comportement thermique d’une maison rurale à faible consommation d’énergie

Notre travail s’intéresse à l’étude expérimentale d’une maison rurale à faible consommation d’énergie, qui a été réalisée dans le cadre du projet MED-ENEC (Efficacité énergétique dans le secteur du bâtiment pour les pays méditerranéens). Ce travail a…
