This paper presents a combined experimental and Computational Fluid Dynamics (CFD) simulation of Micro wind Turbine with 2.28 meters rotor Diameter is performed using the FLUENT 16.2 WORKBENCH. A Micro Horizontal Axis Three Blade Wind Turbine was designed, developed and tested for power performance on new airfoil AFN2016 Designed. The three blades were fabricated from glass fiber with a rotor swept area of 3.14 sq.m for the 1-meter length of the blade and angle of attack experimentally determined to be 5º.The blade is designed for tip speed ratio (TSR) of 7. The power out measured for wind speed from 3.0m/s to 9.0 m/s. The comparison of the CFD and experimental results on the relationship between the power obtained and the wind speed of the wind turbine at the wind from 3-9 m/s. It can be clearly seen that the experimental data match quite well again with the numerical analysis and they both demonstrated that the power of wind turbine increasing with wind speed increases.

Abstract. The power performance and loading dynamic responses of a 2.2 m scaled horizontal axis wind turbine (HAWT) under the IEC 61400-1 transient operational extreme conditions were investigated. Extreme wind shears (EWS) and extreme operational gust (EOG) inflow conditions, generated in the WindEEE dome at Western University. The global forces were measured by a multi axis force balance at the HAWT tower base. The unsteady horizontal shear induced a significant yaw moment on the rotor with similar dynamic loads as the extreme event with no serious effect on the power generation. The EOG severely affected all the performance parameters of the turbine which were highly dependent on the operational TSR and the time duration of the event.
