Les mesures simultanées par thermo-anémométrie de plusieurs grandeurs physiques d'un fluide en écoulement turbulent, nécessite l'emploi d'autant de sondes qu'il y a de variables. Un étalonnage est préalable à toute utilisation de ces capteurs pour…

L'étude consiste à réaliser un procédé de traitement biologique d'une eau de bourbier des puits de forage de Hassi-Messaoud contenant des concentrations excessives en plomb et en gas-oil. Le traitement est effectué au moyen d'un bioréacteur à…

Afin d'étudier la structure fine de la turbulence pariétale en présence de variations importantes de densité, une analyse statistique des données expérimentales, obtenues dans une soufflerie à recirculation, est effectuée. Les résultats montrent que…

Two-dimensional, compressible Euler and Navier-Stokes equations are solved numerically by finite volume method to predict steady and unsteady flows around bluff-bodies. An unstructured grid generator code is linked in an automatic way to the flow…

The penetration of renewable energy resource units in the Electrical Distribution System (EDS) has gradually increased. In addition to that, the interest in the electrification of the transport sector has brought about increasingly significant…

This article examines the best fraction of indium (x) and critical depth (H) of a single junction tandem photovoltaic (PV) cell (InxGa1-xN) in the vein to optimize its electrical efficiency. For better investigation, the optical and electronics…

In this paper, the melting and solidification of n-eicosane as a PCM inside two orientations of square containers is investigated numerically, using enthalpy–porosity method. The study reveals how the melting and solidification rate could be affected…

In Madagascar, the drying of Curcuma consists of exposing them directly to the Sun. This is not always productive. This work aims to provide information on the drying of turmeric by determining the drying curve in order to consider industrial drying.…

In this study, the hygroscopicity and thermodynamic properties of figs were studied to simulate their hygroscopic behavior during storage and drying. The experimental results were analyzed by the nine models of sorption isotherms. The Peleg model was…

The autonomous operation mode of paralleled inverters in microgrids can be intentional or unintentional in order to ensure the continuity of supply. In this mode the voltage and frequency magnitudes are held by local controllers using droop control,…
