“…The full specifications of the wind turbines used are shown in Table . And that is based on the laws of conservation of mass as well as the laws of energy conservation, through the derivation of the Betz equation (the greatest power that can be obtained from wind by a wind turbine operating at 100% efficiency), which applies to horizontal and vertical turbines [5]. In this research, simulation of some turbine parts, including (rotor part, turbine blades as well as turbine shroud), (blade and the shroud, hub) by using the engineering program ANSYS, in order to evaluate the performance of shroud ed turbines and the possibility of establishing them in some areas of Iraq.…”

This study provides an overview of renewable wind energy in Iraq and the possibility of deploying concentrated wind energy technologies to support power generation in agricultural fields. On horizontal wind turbines. The results showed that with the addition of the diffuser, the energy produced shows an increase, and the study also showed that the wind speed in Iraq reaches 8 m per second in the center and south of the country. The study presents wind energy activities in Iraq, and the Iraqi government's attempts to use wind energy. Renewable energy in general, and wind energy in particular.

“…Validation was also obtained by looking at research [27] to compare the CFD and the BEM using the following rotor parameters (Table 6). Validation is performed between the two models, namely CFD and BEM, to ensure that the turbine performance values are reasonable [28]. The computational domain mesh has a significant impact on the accuracy of CFD simulation [29].…”

The rotor is one of the vital components of a wind turbine. In the design of the rotor, the expected result is the most optimal power. This purpose study is to optimization of the Horizontal Axis Wind Turbine power of various parameters such as airfoil, angle of attack, and pitch angle. Airfoils (NACA 4412-2412 T.E. mod, NACA 2412-4412 T.E. mod, NACA 4412-2412 L.E. mod, NACA 2412-4412 L.E. mod), angle of attack (0, 2, 4, 6), and pitch angle (0, 1, 2, 3) are the parameter variations used. The simulation method uses BEM (Blade Element Momentum), and the Taguchi for optimization is based on the L16 orthogonal array matrix. The ANOVA has to determine the contribution of each parameter to the HAWT power generated. Simulation and optimization results show that the most optimal parameter was a NACA airfoil 4412-2412 L.E mod, at 0˚ angle of attack and 0˚ pitch angle, with the resulting power reaching 1015780 Watt. The ANOVA analysis shows the airfoil parameter has the greatest contribution to the rotor power of the HAWT compared to the angle of attack and pitch angle.

The goal of this study is to investigate the performance of a small horizontal axis wind turbine blade at wind speeds of lower than 5 m/sec numerically and experimentally. The rotor blade has a diameter of 0.7m and consists of two airfoils profile: the thin airfoil SD2030 selected at the outboard region, and the thick airfoil E231 at the inboard region. The former airfoil, SD2030, is highly recognized for aerodynamic performance as it is suitable for low Reynolds number (Re), while the latter airfoil E231 is likewise appropriate for low Re flow but has a higher thickness-to-chord ratio which acts as structural support and good strength at the hub. The selected airfoils were analyzed using QBlade software based on XFOIL and Blade Element Theory (BEM) for different Reynolds number. Using a low-speed wind tunnel and Reynolds number ranging from 1x105 to 5x105, experiments at pitch angles of 5ο were conducted to determine the variation in torque and predict blade performance. The results reveal that the turbine with two hybrid different airfoil profiles have achieved a better start-up response at low wind speed of 1.5 m/s and a high-power coefficient of 0.34 with 3.7 tip speed ratio. The turbine can be used to generate a power of 0.5W at 1.5 m/s and a maximum power harvest of up to 20W at a wind speed of 7m/sec. The turbine's performance compared to other small wind turbines from the literatures demonstrate good performance and the results obtained from wind tunnel data were found in satisfactory agreement with the results provided by the BEM code.
