In this paper, an analysis of basic airfoils profile for micro and small-scale horizontal axis wind turbine (HAWT) has been studied for different angle-of-attack and fixed Reynolds number. For turbine blade modeling, the data used is from National advisory committee of aeronautics (NACA) of five digit airfoil series. The comprehensive relationship between optimal angle-of-attack and Reynolds number has been analyzed. A low or high lift-to-drag ratio ( / ) can be identified at different angle-of-attack . The computational fluid dynamics analysis of NACA 63-415 airfoil is carried out at different angle-of-attack at wind speed 5 m/s using ANSYS/Fluent software. The pressure, turbulence and velocity distribution plots have been observed.Index Terms-Angle-of-attack ( ), coefficient of power ( ), horizontal axis wind turbine (HAWT), lift-to-drag ( / ) ratio, national advisory committee of aeronautics (NACA) series, reynolds number (Re) and tip speed ratio (TSR).

“…Today, the HAWT is the much more prevalent form of wind turbine, and the type which is the primary focus of this article. [1] According to experience the major characteristics of wind turbine performance are based on the aerodynamic forces generated by the mean wind. [2] the design of an aerogenerator is essentially based on aerodynamic modelling, the dimensioning of this geometrical form has a high impact on its energy efficiency and, as a result on its economic profitability.…”

The aerodynamic modelling of the wind turbine blades is a vital step in the design of the turbine. Several design methods are available for the aerodynamic design of the rotor, however, in this study a mathematical model based on blade element momentum concept is applied. the purpose of this work is to optimize the distribution of chord and twist angle along the blade span of a 20 KW HAWT using the BEM method, the blade design parameters such as the optimum lift and drag coefficient , chord and twist angle, the axial induction factor(a) and the angular induction factor(a’) of the designed HAWT are codified and estimated using the MATLAB software. The results of the analysis show on the one hand a decrease in chord length and twist angle along the blade length and on the other hand the maximum values that can be achieved by the axial and angular inductions factors are respectively 0.3325 and 0.175. This approach can be effectively implemented for the analysis of HAWTs operating at different characteristics of the designed blade.

Efficient utilization of wind energy depends on careful selection and suitable design of Wind Turbine (WT) blades. Small scale Wind Turbines (SWT) normally operate in the low range of Angle of Attack (AoA). This makes the task even more difficult for designing and optimization of WT blades. This article deals with an airfoil based computational approach to design the blade for a standalone small scale Horizontal Axis Wind Turbine (HAWT). A procedure has been proposed to find the important parameters and analyze the performance characteristics for a three bladed HAWT operating under the wake rotation. Computational code has been written to find optimum blade profile. Twist angle variation, chord length and other related parameters are determined with the help of program. Comparison between different types of airfoil has been made to figure out the most suitable one. Airfoil selection and design approach are intended to make Wind Turbine blade efficient specially under low range of AoA. Characteristics of the Wind Turbine obtained analytically from this procedure are compared with several other reported earlier in some of the literatures. The result obtained by the proposed procedure is simpler and more efficient than BEM theory – a method normally employed for blade design.
