Abstract

In this paper, the Semi-Empirical and numerical methods that can be used to investigate the effects of DYNAMIC STALL in wind turbine blades are compared with each other, and the capabilities of the methods are studied. The Semi-Empirical Leishman-Beddoes (L-B), Snel and ONERA methods have been used, and the finite volume method was being used for numerical simulations. The experimental measurements have been used in order to compare the methods. The lift coefficient is calculated by all the methods, and the drag coefficient has been computed by the numerical and Leishman-Beddoes methods. The parameters have been used in order to compare the methods, are the maximum lift coefficient value, the angle of attack of the largest lift coefficient, the error at upstroke phase and the error at down stroke phase. The results show among the SEMI-EMPIRICAL MODELS; the L-B method has the highest precision to predict the lift coefficient, and although the numerical method can investigate the flow with more details, but the error percentage at the down stroke phase is higher than expectations.The results from the drag coefficient modeling show that the numerical method can predict this coefficient better than the L-B method. The results also can help researchers to select the best DYNAMIC STALL model in order to investigate the wind-turbine aerodynamics.
