Abstract

In order to improve the dynamic stall performance of wind turbine airfoil, the surrogate model method was used to replace CFD calculation to optimize the dynamic stall characteristics of wind turbine airfoil. The airfoil geometry profile was constructed by CST parameterization method, and the aerodynamic parameters at the sample points were obtained by using the optimized Latin hypercube sampling for experimental design. The Gaussian process regression model was established, and the sample points were added according to the maximum improvement expectation criterion to continuously improve the model accuracy. With the reduction of the average torque and drag coefficient of the wind turbine airfoil as the optimization objective and the non-reduction of the average lift coefficient as the limiting condition, Global evolutionary genetic algorithm inspired by nature is used to search for optimization. The results show that compared with the original airfoil, optimization of airfoil aerodynamic performance is better, especially the drag and torque coefficient are reduced 9.57% and 16.6%, respectively; In addition, the development of trailing edge vortex is inhibited by the optimized airfoil, and the dynamic stall is improved to some extent.
