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…

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,…

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…

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…

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…

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…

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…

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…

WUne méthodologie de caractérisation du bilan hydrique d’une serre horticole en régime dynamique a été développée. Un modèle réduit de connaissance a été établi à partir des équations biophysiques décrivant les principaux phénomènes, débouchant sur…

The knowledge of the topography of the seafloor is important for several applications. Image satellites of observation of the earth are the result of the interaction of the electromagnetic radiance with the system sea - atmosphere and sensor. To…
