摘要
风能是一种洁净的可再生能源,对风能的开发已受到广泛的重视.采用商用计算流体力学(CFD)软件FLUENT,对风墙聚能风力机进行三维数值模拟.计算在相同来流条件下,不同尺寸和形状的风墙中风力机的聚能增益比,由此来寻求风墙的尺寸和形状对风机聚能的影响规律.对于影响风机聚能效果的参数采用正交优化方法进行分析和优化,得出风墙形状对聚能效果的影响规律,为风墙聚能风力机的试验和建造提供了依据.
Wind energy is a clean and renewable energy, and much attention is being attracted to the use of wind energy. In this paper, a 3D model of wall augmented wind turbine is established. Numerical simulation is carried out by using a computational fluid dynamics （CFD） software FLUENT. With the same upstream wind speed, the ratio of augmentation benefit of the wind turbine in different sizes and shapes of walls are calculated. Influence of the wall on the augmentation effect and its laws are acquired. The augmentation effects are then analyzed and optimized using the orthogonal method, and the rule of the augmentation effect of the wind walls obtained. The simulation study provides a reference for the experiment and construction of the wall augmented wind turbine.
