“…The design and fabrication of small wind turbine blade with mixed airfoils (NACA63-621 and FX66-S-196) applied on inboard and outboard region based on their aerodynamic characteristics were done [29]. Rotors chord (thickness) distribution and twist distribution were calculated by Eqs.…”

“…Blade designers employ the actual airfoil profile along the span of the blade (which is where power is produced) whereas the root is a shape between the airfoil profile and the circular section of the hub and thus does not contribute to power generation [5]. The efficiency of the rotor largely depends on the blades profile in increasing the lift to generate sufficient torque.…”

In contrast to large horizontal axis wind turbines (HAWTs) that are located in areas dictated by optimum wind conditions, small wind turbines are required for producing power without necessarily the best wind conditions. A low Reynolds number airfoil was designed after testing a number of low Reynolds number airfoils and then making one of our own; it was tested for use in small HAWTs. Studies using XFOIL and wind tunnel experiments were performed on the new airfoil at various Reynolds numbers. The pressure distribution, C p , the lift and drag coefficients, C L and C D , were studied for varying angles of attack, α. It is found that the airfoil can achieve very good aerodynamic characteristics at different Reynolds numbers and can be used as an efficient airfoil in small HAWTs. low Reynolds number, airfoil, small wind turbines, pressure distribution, coefficient of lift, coefficient of drag Citation: Wata J, Faizal M, Talu B, et al.

A general parametric representation function (Shape Function) for wind turbine-dedicated airfoils based on Taylor high-order polynomial series is presented for the first time. The design space and shape control function of the airfoil have been studied. The objective of the high-performance WT (Wind Turbine) airfoils was to maximise the lift/drag ratio at the design angle of attack both in free and fixed transitions. The optimised mathematical model of the airfoils is built combing genetic algorithm and the flow solver RFOIL. The new airfoil family (ranging in thickness from 15% to 20%) with target characteristics were designed for variable-speed operation with pitch control of large megawatt-sized rotors. Wind tunnel experiments for the WT180 airfoil were carried out for both clean and rough conditions. The experimental results for the lift and drag coefficients agree well with the RFOIL predictions. The testing verified the high lift/drag ratio and the high maximum lift coefficient for the WT180 airfoil. The results indicate that this novel design method is feasible to optimise wind turbine airfoils.
