Item APPROCHE EXPERIMENTALE DE LA LONGUEUR DU ROULEAU DU SURFACE DU RESSAUT HYDRAULIQUE DANS UN CANAL PROFILE EN “U” A FOND RUGUEUX(جامعة الوادي - university of el oued, 2013) Ghomri, A; Riguet, F; Debabeche, MThis study aims to experimentally evaluate an experimental approach to the length of the roller surface of the hydraulic jump controlled by threshold, moving in a channel profile 'U' rough bottom roughness for different tested. a functional relationship in dimensionless term, linking the different characteristics of the projection, showing the effect of the roughness of the channel bottom was obtainedItem SIMULATION PAR FLUENT DU REFROIDISSEMENT DES AUBES D'UNE TURBINE A GAZ(جامعة الوادي - university of el oued, 2012) Mansouri, M.T; Belghar, NThis article concerns a study analytically and numerically the cooling of the dawn of a gas turbine. We used the Fluent software to simulate the aerodynamic effects and the thermal influence on the blade. We are interested primarily in the theoretical study of this technique applied to film cooling of a flat plate and then looking at the numerical simulation by Fluent model with a k-ε turbulence standard was used to model the turbulent flow where there is much more interested in the thermal aspect of this type of flow trying to explore the effect of temperature on the blade.Item SIMULATION FOR STRATEGY OF MAXIMAL WIND ENERGY CAPTURE OF DOUBLY FED INDUCTION GENERATORS(جامعة الوادي - university of el oued, 2012) Tria, F; Ben Attous, DIn the control of the wind generation, the maximal power point tracking (MPPT) control plays important role in the efficiency. This paper presents the simulation results of the MPPT control based DFIG model. At first, it analyzes the vector-control scheme for the MTTP, which results in independent control of active and reactive power of the generator. And then, it develops the MPPT controller implemented on the rectifier and inverter based on PI controlItem MODÉLISATION ET RÉSOLUTION NUMÉRIQUE DE L'ÉQUATION DE POISSON EN 2D PAR LA MÉTHODE DE DIFFÉRENCE FINIE CAS DE L'ÉQUATION DU TRANSFERT DE LA CHALEUR(جامعة الوادي - university of el oued, 2012) Benhissen, N; Khechekhouche, AThe objective of this work is to solve the Poisson equation by the finite difference method is therefore to provide an approximate solution of the actual behavior of a physical phenomenon. Such as the equation of heat transfer. We will take as a model of square/rectangular plate, with different boundary conditions and we will specify also the values boundaries (the Dirichlet condition). The analysis is based on the simulation results based on certain criteria and choice of parameters that comes into play in the equation, this will give us a good understanding of the manipulation of these parameters and thus understand what is happening on environment studiedItem CORROSION INHIBITION OF CARBON STEEL XC70 IN H2SO4 SOLUTION BY FERROCENE DERIVATIVE 4-(FERROCENYLMETHYLAMINE) BENZONITRILE(جامعة الوادي - university of el oued, 2012) Zaiz, T; Lanez, TIn this work, we studied the efficiency of corrosion inhibition of carbon steel XC70 in H2SO4 0.5 M solution using ferrocenyl compound prepared in our laboratory, this compound is: 4- (ferrocenylmethylamine)benzonitrile (FC). The inhibitory potential of this compound was determined by electrochemical techniques based on Tafel segments. The results show that the studied compound has an efficiency of inhibition which depends on its concentration the adsorption of these compounds on the surface of the metal is a chemical adsorption. The compound FC had the best ability of inhibition at a concentration of 30 ppm (IE = 75.36%).
