Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
The Solar Energy and New Energies Research Institute (IRESEN), founded in February 2011, is a Moroccan institute for applied solar energy and new energy research which is positioned at the applied research and technology to strengthen the link between industry and universities, engineering schools and research centers. The institute set-up an international test and research platform for renewable...
Solar thermal energy is free and renewable. It can participate in the economy of energy, which therefore contribute to reducing energy costs. We present in this study a solar water heater model with a glazed flat plate detector. This produces hot water using solar thermal energy, which, therefore, could help reduce energy costs. The relevance of this work is the realization of solar water heater....
To compare the effect of the annealing and testing temperature, LiMn1.4Ni0.4Co0.2O4 spinel material was synthesized with the combustion method using the sucrose as fuel followed by an annealing at three different temperatures 700°C, 800°C and 900°C. The electrochemical properties were investigated both at room temperature and 55°C under different electrochemical rate. The spinel sample was characterized...
In this paper the dynamic effects of quantum well laser (QWL) has been investigated. This study is based on solving the numerical simple rate equations according to cavity length effect. Using these equations the photons and carriers densities and the output power can be determined. It has been found that the output power becomes more important at lower cavity length. Obtained results exhibit that...
Biodiesel was synthesized at large scale (400L by Batch). The 1H-NMR, 13C-NMR, gas chromatography, and FT-IR analyses of the final product confirmed that in the chosen experimental conditions, the reaction is total. The biodiesel does not contain traces of glycerol. The biodiesel quality parameters that are borderline do not pose any particular problem. The electricity generator diesel engine are...
The objective of the study is to simulate the insert effect of phase change materials inside partition wall that separates a central local having variable temperature and four adjacent conditioned rooms. Comparative study of thermal behavior of two configurations of the wall is conducted. The first configuration, considered as reference case is formed only by the concrete. The second one is provided...
ZnO thin films were deposited on either indium tin oxide-coated glass by the electrodeposition process, using zinc chloride as precursor and continuous flowing air as precursors. The effect of concentration variation on the structural and morphological of ZnO films was studied and the optimum deposition conditions have been outlined. The kinetics of the growth of the films have been also investigated...
The infrared thermography technique developed in the present study was successfully applied to determine the scale thicknesses in the steel pipe. By finite element method we have calculated the infected pipe surface temperature. We have developed a model for estimation the thickness scale on the inner surfaces pipe. Pipe dimensions and scale layer are taken as geometrical parameter. We have studied...
Temperature effect on a free vibrating airfoil is investigated in this paper. Calculations are based on solving the Navier Stokes equations coupled to solid dynamic equations; the ALE formulation of RANS equations is applied. Turbulence is modeled by the SST k-ω model and the Flap/lead-lag motion is considered. Results show that high temperatures induce degradation of aerodynamic performances of the...
The accumulation of dust on the surface of the solar reflectors is threatening to decrease the planned energy output of the concentrated solar power (CSP) plants deployed in the MENA region. This paper investigates the soiling behavior of CSP aluminum mirrors exposed under natural environment, from 26-06-2014 to 29-12-2014 in southwest Morocco, with the reflectance of the exposed mirrors being measured...
This work deals with the modeling and optimization of the CuInGaSe/CdS based structure, for photovoltaics. In this study we took into consideration the effect of the concentration of the alloy and the temperature on the strain bandgap, the absorption and efficiency of the structure. It has been shown that the gallium concentration x varies the strain bandgap energy, these two parameters significantly...
In this work, CuInS2 (CIS) thin films were prepared by spray pyrolysis method, and optical properties were investigated. CuInS2 in the form of films is prepared at different deposition conditions by a simple and economical spray pyrolysis method. Optical constants such as band gap Eg, extinction coefficient k, refractive index n, and dielectric constants e1 and e2 were determined from the measured...
Transparent conductive SnO2 films were deposited on glass substrates by sol-gel spin coating method. Taguchi method was used to find the optimal deposition parameters, three influential parameters were selected in this experiment, Concentration of Tin (II) ions, annealing temperature and pre-annealing temperature. By employing the analysis of variance, we found that the annealing temperature and the...
We describe a Smart City, self-powered, water monitoring solution that uses low-cost water turbines. These can generate up to ∼ 4 W electrical power whilst reporting flow rates at UK domestic water pressure levels. This permits the novel use of stand-alone, remote Apache Spark Streaming as a distributed alternative to the conventional hierarchical Smart Grid. A future Smart City will have innovative...
This paper presents the development of power capability limits of the squirrel cage asynchronous generator (SCAG) integrated in the wind energy conversion system (WECS) and connected to the power network through a RL filter. The reactive power capability is developed in order to limit the active and reactive power imposed by the operator and the reactive power required to maintain the grid voltage...
This research is a concept study for a photovoltaic power plant on an Algerian site, this plant is connected to the electrical distribution network of low or medium voltage. it follows that the study of system simulation in its entirety, would be used for this purpose the computer software PVSYST. our work involves the design of 1 MWc photovoltaic plant in Aïn-melh M'sila where there favorable weather...
In this study, we compare the structural properties of the three phases wurtzite (B4), zinc blende (B3), and rocksalt (B1) of ZnO using the generalized gradient approximation (GGA) and the modified Becke-Johnson TB-mBJ potential to compare their electronic and optical properties. It's found that the wurtzite phase is energetically the most stable. Zinc blende and wurtzite structures show similar electronic...
