摘要
以改进Glauert理论为目的,以有限叶片数、变环量及扩散状的尾流模型为依据,建立和求解描述该模型的积分微分方程,获得一种确定水平轴风力机叶片气动外形设计的新方法。应用该设计方法对某1.5MW风力机叶片进行气动外形设计,并将其气动计算结果与其他方法的结果进行比较,以说明所给方法的有效性。该研究成果为大功率风力机叶片的设计提供了理论依据,为风力机叶片的研究和实际应用开拓了前景。
Base on limited number of blades, mutative circulation and expanded vortex aerodynamic model, the in-tegral differential equations describing the model was set up and solved to improve Glauert theory and a new method for designing the aerodynamic configuration of horizontal-axis wind turbine blade was obtained. Then the optimum design of a 1.5 MW wind turbine was given as an example and the calculation results were compared with other re-suits to demonstrate the effectiveness of the new method. The research results can provide theoretical basis for the design and exploitation of high-power wind turbine blade and open up a broader vista of research and practical ap-plications for wind turbine blade.
