Composite materials find extensive usage in industrial applications. Howeer, they are susceptible to gradual damage over time. In this study, we explored the cracking processes in jute fiber-reinforced composite sheets subjected to uniaxial tension at varying displacement speeds (10, 20, and 30 mm/min) using Abaqus software. The composite plate dimensions are 25×35×10 mm³, with a 7 mm crack length. Our findings indicate that crack propagation in vehicle plates is influenced by mechanical properties relative to load, specifically through increased travel speed. We observed stress concentration around the crack, and the displacement speed significantly affects crack behavior. The cohesive J-integral was derived through finite element analysis, revealing a 90.90% relative error in the mean absolute value ΔJ across the five integral paths for the two sample types. Subsequently, five potential end conditions were assessed for further analysis, considering different boundary conditions: Simply supported (SSSS), two opposing sides clamped (SFSF), Clamped-Simply-ClampedSimply (SCSC), two opposing sides clamped (CFCF), and all sides clamped (CCCC). Additionally, three different types of tensile actions in the y-direction were considered

This paper presents a numerical study of natural convection in an annular cavity filled with a hybrid nanofluid under the influence of a magnetic field. This study is significant for applications requiring enhanced thermal management, such as in heat exchangers, electronics cooling, and energy systems. The inner cylinder, equipped with fins and subjected to uniform volumetric heat generation, contrasts with the adiabatic outer cylinder. This study aims to investigate how different nanoparticle combinations (Fe3O4 with Cu, Ag, and Al2O3) and varying Hartmann and Rayleigh numbers impact heat transfer efficiency. The finite volume method is employed to solve the governing equations, with simulations conducted using Fluent 6.3.26. Parameters such as volume fraction (ϕ2 = 0.001, 0.004, 0.006), Hartmann number (0 ≤ Ha ≤ 100), Rayleigh number (3 × 103 ≤ Ra ≤ 2.4 × 104), and fin number (N = 0, 2, 4, 6, 8) are analyzed. Streamlines, isotherms, and induced magnetic field contours are utilized to assess flow structure and heat transfer. The results reveal that increasing the Rayleigh number and magnetic field enhances heat transfer, while the presence of fins, especially at N = 2, may inhibit convection currents and reduce heat transfer efficiency. These findings provide valuable insights into optimizing nanofluid-based cooling systems and highlight the trade-offs in incorporating fins in thermal management designs.

To produce electricity from the wind, horizontal axis turbines exceeding 80 m in height are often used. Entirely immersed in the atmospheric boundary layer, these wind turbines undergo the same changes as the speed of the wind in a wind farm. In this context comes our study for the effect of the atmospheric boundary layer on the energy production for a single wind turbine, then generalize it to all the wind turbines of the farm. Using the logarithmic profile of wind speed in the atmospheric boundary layer, data from two types of wind turbines; NREL-V and ENERCON-E2 are introduced in a computer program for the calculation of the developed power. The results obtained are compared and discussed.

The accurate prediction of total energy output in a wind farm hinges on the specific arrangement of wind turbines. Relying solely on a wind speed model that assumes uniform and unidirectional conditions appears insufficient for achieving a detailed understanding of optimal turbine placement to produce maximum energy. In this context, we present our efforts to develop a calculation method for precisely situating wind turbines within a wind farm. This method leverages pseudorandom number generation as a mathematical optimization approach, implemented through a Matlab program. More specifically, our proposal introduces a more comprehensive and realistic wake model. This model factors in various variables such as the atmospheric boundary layer, ground roughness, and turbulence. By doing so, it aims to provide a significantly more accurate prediction of the effects of wind turbine interference at the site and, consequently, minimize wake-related impacts. Our simulation results have been meticulously analyzed using data sourced from NREL turbin

With the world’s growing demand for energy, renewable energy production has become important in providing alternative sources of energy and in reducing the greenhouse effect. This study investigates the aerodynamics and performance of the WG/EV100 micro–Horizontal Axis Wind Turbine (HAWT) using Computational Fluid Dynamics (CFD). The complexity of VAWT aerodynamics, which is inherently unsteady and three-dimensional, makes high-fidelity flow models extremely demanding in terms of computational cost, limiting the analysis to mainly 2D Computational Fluid-Dynamics (CFD) approaches. This article explains how to perform a full 3D unsteady CFD simulation of HAWT. All main parts of the WG/EV100 HAWT were designed in SOLIDWORKS. Only the blade design was reverse engineered due to the unavailability of the CAD model and the complexity of its geometric characteristics. The impeller blade is scanned using a Coordi-nate Measuring Machine (CMM), and the obtained 3D scan data are exported from the PC-DMIS software to GEOMAGIC design X to obtain a CAD model of the blade.

Abstract: By increasing their electricity production capacity, this work focuses on a new wind farm configuration study currently in service. More specifically, a study that aims to enlarge the production area of the ventilated sites by implanting more wind turbines in optimal positions behind the existing turbines. In order to achieve this goal, we use Jensen's linear wake pattern to describe the behavior of wind speed in wake, as well as a method based on the generation of a sequence of modified pseudo-random numbers as Mathematical approach to optimize the location of the wind turines. To perform numerical simulations, a program under MATLAB has been developed using the characteristics of the Gamessa G52 turbine and the data of the site in the production of Kaberten in Algeria. The results obtained from this study are presented and discussed.

In the atmospheric boundary layer, the uniform and unidirectional wind speed does not seem to be valid; it has a logarithmic or exponential profile. Close to the ground, this speed is slowed down by the roughness of the ground and the presence of obstacles, while going uphill, the wind speed becomes more and more important and reaches a determined value. For the power produced by the wind turbine in the atmospheric boundary layer, the moment of force exerted by the wind is not the same over the entire rotor actuator disc. In this context and to remedy this problem, we present in this work a method which aims to calculate the power developed by a wind turbine where the wind speed is not constant in the atmospheric boundary layer. This method is based on the discretization of the rotor actuator disc into elementary surfaces, using the power characteristic curve which corresponds to given wind speeds of such a wind turbine. By a computer program developed, the elementary power is calculated in each element of discretized surface, then, the total power of the wind turbine in atmospheric boundary layer is only the sum of the elementary powers. To show the validity of this method, the results obtained in this study are analyzed and discussed. It should be noted that the power in each discretized surface element is different from that of the others, because the wind speed is different at each height

Inspired by the functioning of neurons in the brain, neural networks are tools widely used in artificial intelligence in solving statistical problems. To this end, in wind energy, the wind is in perpetual variation, in order to model it and predict its intensity from its average annual speed, we present in this study a method based on the use of artificial neural networks. Using the accumulation of a period of 10 years of measurements of the average annual wind speed of a site in the region of Kaberten, a computer program has been developed under MATLAB to estimate the wind in the years to come. This program makes it possible to predict the wind speed at 10 m from the ground in the year following the measurement period. The results obtained by this method on the Kaberten site are analyzed and discussed.

An essential challenge for the future of composite materials is to make their manufacture and use compatible with increasingly demanding environmental expectations. In this context, the replacement of mineral or synthetic fibers by plant fibers is of great interest. However, the latter must comply with the same specifications, particularly in terms of mechanical properties. Thanks to their low density, their biodegradability as well as their abundance, the use of these fibers is interesting from Thanks to their low density, their biodegradability as well as their abundance, the use of these fibers is interesting from thanks to their low density, their biodegradability as well as their abundance, the use of these fibers is interesting from economic and environmental point of view. The dimensions of the fiber, such as diameter, are essential elements when calculating the mechanical parameters of the plant fiber. Among the techniques used to measure the diameter, one can use the optical microscope, the software ImageJ and the density. Theoretically, similar failure parameters should be obtained when different techniques are used. However, the experimental data show various parameters according to different used techniques. In this work, we carried out several experiments on natural fibers in order to determine the fracture parameters in static traction by calculating the diameter of the fiber by two ways: density method and optical method. The results reveal that the failure parameters are dependent on the diameter, hence the suitable technique plays a crucial role.

The main objective of this work is the analysis and the modeling of the wind by all the characteristics in order to predict the variations of the intensity of its annual average speed in the atmospheric boundary layer during a year using 'a new method based on artificial neurons. By introducing data and cumulative wind speed measurements over several decades from such a windy site, this method, developed on MATLAB, makes it possible to estimate the annual wind speed at 5 m from the ground in the years to come. The simulation results obtained in this work are analyzed and validated by comparing them with the results measured on this site in the years preceding the measurement period.

In this paper, with the goal of maximizing the power production of a wind farm and reducing the wake effect resulting from front-end turbines, we present a new optimization method based on the generation of pseudo-random numbers as a mathematical approach; we have used this method along with the Jensen linear wake model in order to study optimal wind turbine positioning in a farm of given dimensions. For this purpose, a computer program has been developed to carry out numerical simulations based on the maximum total power produced. Using a typical wind turbine for uniform and unidirectional wind speed, the simulation results that we have obtained are presented and discussed. Compared to previous works based on genetic algorithms and viral basis methods, this optimization has yielded recorded enhancements of up to 6.5% on resulting wind farm power. Furthermore, we have found that an optimum number of wind turbines can be properly determined for any given wind farm.

In a windy site, under the effect of the wake, the too dense grouping of wind turbines would lead to a speed deficit and a considerable reduction in power, which affects the overall performance of the wind farm. To describe the evolution of the wind speed in the wake, several models were used without taking into account the turbulence. For this purpose, and in this work, we present a study that aims at the effect of turbulence on the power of a wind turbine, this study is based on the introduction of data and the characteristics of the wind turbine ENERCON E2 and the Using a more comprehensive wake model that accounts for ambient and added wind turbulence is the Ishihara model. The simulation results obtained from the developed power, were presented and compared with those without turbulence.

The configuration of a wind farm depends mainly on the wind potential and the disposition of the wind turbines in this park. The windiest site is the most favorable for a future installation of wind turbines for the production of electricity, also, in this same site, a too dense arrangement would lead to considerable of power losses under the effect of wake. In this context, it is presented a research work that consists of determining the installation conditions of a wind farm; evaluating the wind farm through measurements of wind speed and the location of wind turbines in the park to minimize the effect of wind turbine interference. In order to do this, an evaluation study of the wind potential for the implementation of a wind farm based on the quantification of the wind in speed and directions firstly proposed. Secondly, a method for optimizing the positioning of wind turbines in a wind power farm is used based on the introduction of the Jensen wake model and the application of the iterative pseudo-random distribution approach of the turbines in the site. Simulation results are presented and discussed using data from the Kaberten site in Algeria and the characteristics of the GAMESA G52 wind turbine.

Dans un parc éolien, il est bien connu que la performance globale du parc est fortement liée aux types d’arrangement des aérogénérateurs dans le site. Un arrangement trop dense entraînerait des pertes considérables de puissance. Dans ce contexte, intervient notre travail, pour déterminer la micro-localisation optimale des éoliennes dans un parc et minimiser l’effet dû aux interférences de sillages des éoliennes. Pour ce faire, nous proposons un modèle numérique, basé sur la description linéaire du sillage, et la méthode d’optimisation de Monte Carlo, afin d’étudier la micro-localisation optimale des turbines en fonction des caractéristiques aérodynamiques et des espacements entre les turbines. La validité des résultats de simulation a été étudiée en utilisant les données expérimentales de NREL
