摘要：
In order to improve the aerodynamic performance of airfoil with wind driven water pump, an adaptive simulated annealing genetic algorithm(GASA) is designed based on the idea of adaptive simulated annealing genetic algorithm. which is applied to the optimization design of wind driven water pump and the airfoil. Self-adaptive genetic algorithm of simulated annealing (GASA) can make up for the shortcoming of low precision of local search when using traditional genetic algorithm (GA) for optimization design, and improve the efficiency of optimization algorithm. In this paper, the living example of optimization design of small-thickness airfoil profile NACA4412 used in wind driven water pump was provided. The lift-drag ratio of the airfoil profile optimized by the self-adaptive simulated annealing genetic algorithm and genetic algorithm is 4.02% and 3.89% higher than that of the standard airfoil respectively, which verified the effectiveness of the designed self-adaptive simulated annealing algorithm in the optimization design of wind driven water pump airfoil profile. The wind tunnel experiment is carried out on the optimized airfoil profile, and the experimental results show that the variation trend of surface pressure and velocity of the airfoil profile is basically consistent with that of the simulation results, which verifies the aerodynamic performance of the optimized airfoil profile in the actual environment. © 2021, Solar Energy Periodical Office Co., Ltd.
