Abstract


, Energy and environmental protection has become an urgent need to solve the problem of human survival and development , governments pay more attention to sustainable energy development, utilization . Wind energy as a clean and renewable energy , and has broad application prospects . Wind power is the world's most technologically mature a wind energy the way , where resistance - type vertical axis wind turbine structure is simple , adaptable , to be more favored in the field of small-scale wind power generation . However , due to the wind energy utilization coefficient lower disadvantage , the development of the wind turbine has been limited. To improve the resistance -type vertical axis wind turbine , wind energy utilization coefficient , based on the principle of wind turbine captures wind energy , design a rectifier type wind turbine , the wind turbine fairing wind wheel . Fairing can be increased acting on the wind turbine blades on the wind speed , and torque , reducing the on resistance of the blade by adjusting the direction of flow , in order to achieve the purpose of rectifying and enhance the performance of the wind turbine . The rectifier type wind turbine efficiency performance structural parameters papers , research program to determine the structural parameters optimized . By means of computing fluid dynamics software Fluent numerical calculation of two - dimensional flow field of wind turbine , wind turbine under the different structural parameter combinations CP ?? Curve . Simulation results , analysis of the fairing on the flow field of wind turbine and wind turbine structural parameters on the impact of wind energy utilization factor . On this basis , the optimal choice of the structural parameters of the wind turbine . To study the actual performance of the rectifier wind turbine , the paper design , manufacture prototype wind turbine , the application of a simple wind tunnel or without fairing wind machine hair Experimental results show that the installation of the fairing , wind turbine the performance has been improved significantly .
