The rotor is one of the vital components a wind turbine. In design rotor, expected result most optimal power. This purpose study to optimization Horizontal Axis Wind Turbine power various parameters such as airfoil, angle attack, and pitch angle. Airfoils (NACA 4412-2412 T.E. mod, NACA 2412-4412 L.E. mod), attack (0, 2, 4, 6), 1, 3) are parameter variations used. simulation method uses BEM (Bla...


 This paper describes a systematic approach to building an intelligent solar Tracking system (ISTS), for improving the performance of panels. The ISTS is hybrid hardware / software prototype, which automatically provides best alignment panel with sun, get maximum output (electricity). method increasing power collection efficiency by developing device that tracts sun keep at right angle it...

The actuator line model is used to study the vertically staggered wind turbine cluster composed of horizontal- and vertical-axis turbines (HAWTs VAWTs) in a tandem layout. We consider three simple configurations, including VAWT upwind HAWT (V + H), downwind (H V), between two HAWTs V H). A installed can not only generate power by itself but also enhance generation HAWT, total increases about 10...

With the world’s growing demand for energy, renewable energy production has become important in providing alternative sources of and reducing greenhouse effect. This study investigates aerodynamics performance WG/EV100 micro–Horizontal Axis Wind Turbine (HAWT) using Computational Fluid Dynamics (CFD). The complexity VAWT aerodynamics, which is inherently unsteady three-dimensional, makes high-f...

Three different horizontal axis wind turbine (HAWT) blade geometries with the same diameter of 0.72 m using the same NACA4418 airfoil profile have been investigated both experimentally and numerically. The first is an optimum (OPT) blade shape, obtained using improved blade element momentum (BEM) theory. A detailed description of the blade geometry is also given. The second is an untapered and ...

The main purpose of this study is to develop an understanding the aerodynamic performance a horizontal axis wind turbine (HAWT) operating in dusty environment, with various concentration dust flow domain. computational analysis was accomplished by commercial fluid dynamics (CFD) code ANSYS Fluent 16.0. Initially, user-friendly developed application utilized for optimum blade geometry special ch...

The Betz theory expresses that no horizontal axis wind turbine can extract more than 16/27 (59.3%) of the kinetic energy of the wind. The factor 16/27 (0.593) is known as the Betz limit. Horizontal Axis wind turbine designers try to improve the power performance to reach the Betz limit. Modern operational wind turbines achieve at peak 75% to 80% of the Betz limit. In 1919, Albert Betz used an a...

The aim of this research work is to modulate the pitch angle both types wind turbines based on fuzzy logic control (FLC), as changes in have various functions horizontal and vertical axis turbines. For HAWT, applied shield electrical components turbine when speed exceeds rated without shutting down turbine. FLC used angular velocity using two inputs one output with three membership for output. ...

This study presents experimental and numerical investigation for the effect of number blade (solidity) on power thrust coefficients a small-scale horizontal-axis wind turbine HAWT. An set- up was installed rotors with different blades, i.e. three, five six, at tip speed ratios, in closed-circuit open-test section tunnel. The obtained results from CFD simulations were performed to compare data m...
