Wind turbine design and its aerodynamic issues

针风力机设计中的复杂多变量、多目标和多约束优化问题,提出一种基于Pareto理论的风力机多目标设计框架,并以1.5 MW大型风力机叶片设计为例,讨论了风力机多目标一体化设计的基本特点.然后由此引出风力机设计中至关重要的气动计算方法和非定常气动力建模面临的挑战,概述了风力机空气动力学的复杂性,介绍了在风力机空气动力学计算方法和气动建模方面取得的进展和存在的问题.

A multi-objective design framework is presented based on Pareto theory for complicated multiple variables, multiple objectives and multiple constraints in wind turbine optimization. The basic features of the integrated optimization design are discussed through a 1.5 MW large-scale wind turbine blade design as an example. Key issues in both the wind turbine aerodynamic calculation methods and the unsteady aerodynamic modeling are then introduced with a summary of the complexity of wind turbine aerodynamics, followed by a brief review on progress and challenges in the aerodynamic calculations and models one by one.
