Abstract EN
In this research work, the investigation and optimization of small horizontal axis wind turbine blade at low wind speed are pursued.
The experimental blades were developed using the 3D printing additive manufacturing technique.
The airfoils E210, NACA2412, S1223, SG6043, E216, NACA4415, SD7080, SD7033, S1210, and MAF were tested at the wind speed of 2–6 m/s.
The airfoils and optimum blade geometry were investigated with the aid of the Xfoil software at Reynolds number of 100,000.
The initial investigation range included tip speed ratios from 3 to 10, solidity from 0.0431–0.1181 and angle of attacks from 2o to 20o .
Later on, these parameters were varied in MATLAB and Xfoil software for optimization and investigation of the power coefficient, lift coefficient, drag coefficient, and lift to drag ratio.
The cut-in wind speed of the rotors was 2 and 2.5 m/s with the winglet-equipped blades and without winglets.
It was found that the E210, SG6043, E216 NACA4415, and MAF airfoil displayed better performance than the NACA 2412, S1223, SD7080, S1210, and SD7003 for the geometry optimized for the operating conditions and manufacturing method described.
