Abstract

The design of an airfoil in the wind turbine and optimizing the blades is fundamental in a wind turbine aerodynamic performance. In this paper, the effect of the multiple multi-elements on the aerodynamic performance of airfoil is investigated. These multi-element configurations are expected to offer better performance of the wind turbine by maximizing the lift and drag coefficients. Based on the case studies analysis, the multi-elements have shown that the modified design results in high values of the power coefficient at low-speed ratios. This effect is attributed to the cancelation of the negative torque on the turbine rotor observed at some azimuthal angles of the turbine rotor. The results from the case studies stated that the change in optimal shape mainly comes from the variation in lift coefficient and attack angle corresponding to the highest lift-to-drag ratio. Furthermore, The aerodynamic configurations of the multi-elements can help in increasing the efficiency of a wind turbine.
