Experimental investigations and numerical analysis using Ansys CFD software of the effect different blade configurations on performance small-scale wind turbines are presented in this paper. A complete test rig turbine is built, three-dimensional computational model rotor system created simulated Realizable K−ε turbulent to evaluate four types (Twisted blades with NACA0012, Straight (untwisted) Twisted NACA4418, NACA4418). The experimental has been carried out at various speeds range 2 m/s 8 study variation power coefficient for speed choose most effective design blades. results show that solution over predicts produced compared field all tested configurations. maximum deviation was around 15 percent between decreased increasing speed. Untwisted NACA0012 suitable small scale based results, giving an average actual (Cp = 0.41). Compared configuration, simple manufacturing minimum cost.
