In making a horizontal type wind turbine, of course, it is necessary to analyze it in depth, one of which is by predicting the production of wind energy produced by the wind turbine to estimate the wind power in the wind turbine which will later be applied. Wind energy sources that are commonly used are located in rural areas, fields and even there is such a large amount of energy that it is sometimes difficult to reach the power grid and other large areas including the roofs of high-rise buildings. There are many analytical models in wind energy estimation, one of which is often done by many researchers, namely by using the Weibull distribution method. From the measurement results that as many as 1516.37 kWh with a 1 kW wind turbine with a radius of 1 meter (capacity factor 30.09%). Modeling wind turbine blades with NACA 4412 using Qblade software to determine the torsional angle of the blade to be applied so that it is obtained that the torsion angle from the base and The tip of the blade has a tilt angle of 19.05◦ to 6.96° with a maximum Cp of 0.5 this is a pretty good value in designing wind turbine blades.

The demand for wind and other forms of clean energy is increasing in the US and throughout the world. Wind energy is also expected to provide 14.9% of the global electricity demand by 2020. Under this scenario, a significant amount of wind turbine blades (WTBs) will continue to burden our current landfills until a viable recycling strategy is found. Repurposing or recycling of end- of-use wind turbine blade material will provide both economic and environmental attributes.

The review reflects physical solutions for de-icing, one of the main problems that impedes the efficient use of wind turbines for autonomous energy resources in cold regions. This topic is currently very relevant for ensuring the dynamic development of wind energy in the Arctic. The review discusses an effective anti-icing strategy for wind turbine blades, including various passive and active physical de-icing techniques using superhydrophobic coatings, thermal heaters, ultrasonic and vibration devices, operating control to determine the optimal methods and their combinations. After a brief description of the active methods, the energy consumption required for their realization is estimated. Passive methods do not involve extra costs, so the review focuses on the most promising solutions with superhydrophobic coatings. Among them, special attention is paid to plastic coatings with a lithographic method of applying micro and nanostructures. This review is of interest to researchers who develop new effective solutions for protection against icing, in particular, when choosing systems for protecting wind turbines.

Average Deviation

Abstract In the past ten to fifteen years wind energy remerged on the world scene with a very healthy growth rate, it has outstripped photovoltaics (solar cells) as the world’s fastest growing energy source, with a growth rate in excess of 30 percent per annum. No longer just a “nice idea for the future” Wind energy is becoming a mainstream energy source for many countries. The proposed paper will present a procedure (using numerical methods) for the design and analysis of Horizontal Axis Wind Turbine (HAWT) rotors. To ascertain the accuracy and to determine where further improvements could be initiated; numerical findings were then compared with published experimental test data and the compression showed an average deviation of less than 3% and therefore the simplifying assumptions made for the prediction of fluid behavior over an airfoil section was justified. Once the approach was validated and standardised a comprehensive airfoil design was produced. A computational fluid dynamic code coupled with a simple numerical algorithm aided the inverse design procedure. The final design was well proportioned and was theoretically able to meet the stated objective function and satisfied all the imposed constraints (manufacturing and geometrical). The geometrical data was then generated in a form suitable for manufacture using manually and numerically controlled machines.

Utilization of wind power in Indonesia is less attractive compared with utilization of conventional fuel. This is because the price of wind energy is not competitive when compared with fossil energy prices, and as a result of the implementation of energy pricing policy through subsidies. Before designing the Wind Energy Conversion System, simulation of computational fluid dynamics needs to be done in order for reducing designing time and cost. In this research, modeling and simulation work has been done to figure out the optimum aerodynamics coefficient of wind turbine blades at different Reynolds number. This blade is a modification of standard airfoil of NACA 4415. The aerodynamics coefficient of modify and standard airfoil is then compared. FLUENT software and Spalart-Allmaras Turbulent Model are used in this work. Based on the comparison of the coefficient of aerodynamic, modification NACA 4415 airfoil has better performance at Reynolds number of 4.1 x 104 to 2.5 x 105. The experiment results also showed that based on a numerical study of the modification NACA 4415 airfoil can be used as a basis for the establishment of wind turbine blades.

Abstract The ever-increasing demand for energy necessitates the use of renewable energy sources such as wind energy. Wind turbines are widely used to convert wind energy into electrical and mechanical energy, with designs constantly being improved to increase efficiency and power. The turbine blades are considered as long cantilever structures, which are susceptible to vibrations that reduce the performance of the turbine. Honeycomb and closed cell foam sandwich structures have been previously used for turbine blade planking. In this research work, the use of an auxetic core instead of a honeycomb core is proposed for use in wind turbine blades to reduce structural vibrations. Different auxetic topologies are investigated and compared with the half-power method, and their vibration and damping behavior is analyzed in comparison with the conventional honeycomb core. It has been shown through FEA simulations that both the damping ratios are higher and the vibration amplitudes are lower for the auxeticc as compared to conventional closed celled structures like honeycombs.

Delamination at ply drops in composites with thickness tapering has been a concern in applications of carbon fibers. This study explored the resistance to delamination under fatigue loading of carbon and glass fiber prepreg laminates with the same resin system, containing various ply drop geometries, and using thicker plies typical of wind turbine blades. Applied stress and strain levels to produce significant delamination at ply drops have been determined, and the experimental results correlated through finite element and analytical models. Carbon fiber laminates with ply drops, while performing adequately under static loads, delaminated in fatigue at low maximum strain levels except for the thinnest ply drops. The lower elastic modulus of the glass fiber laminates resulted in much higher strains to produce delamination for equivalent ply drop geometries. The results indicate that ply drops for carbon fibers should be much thinner than those commonly used for glass fibers in wind turbine blades.

Wind energy is one among the most promising renewable energy sources, and hence there is fast growth of wind energy farm implantation over the last decade, which is expected to be even faster in the coming years. Wind turbine blades are complex structures considering the different scientific fields involved in their study. Indeed, the study of blade performance involves fluid mechanics (aerodynamic study), solids mechanics (the nature of materials, the type of solicitations …), and the fluid coupling structure (IFS). The scope of the present work is to investigate the mechanical performances and structural integrity of a large offshore wind turbine blade under critical loads using blade element momentum. The resulting pressure was applied to the blade by the use of a user subroutine “DLOAD” implemented in ABAQUS finite element analysis software. The main objective is to identify and predict the zones which are sensitive to damage and failure as well as to evaluate the potential of composite materials (carbon fiber and glass fiber) and their effect on reduction of rotor’s weight, as well as the increase of resistance to wear, and stiffness.
