项目摘要
In order to promote off-shore wind farms in Japan, there are many technical problems such as the forecast of the potential and the unsteady nature of the wind near the coast, the shape of the aerofoils appropriate to the high speed wind turbines, the prediction of the noise and so on. This research project was carried out to obtain the fundamental data for the design and development of the off-shore wind farm by three teams of different universities. The results of each team are summarized as follows :Nagoya University Team : The wind measurements were carried out in the field to clarify the turbulence characteristics of the wind flow over a complex terrain and the effects of the slope on the turbulence was evaluated from the power spectrum and spatial coherence of the wind fluctuation. Turbulence intensity becomes larger with the increase in the slope steepness and the fluctuation exhibits higher level in the range of high frequency.Tokyo University Team : Using a large-eddy simulation and direct noise simulation, the flow and acoustic field around a wind turbine blade were calculated, and the aerodynamic performance and acoustic emission are predicted for the actual tip shape.Mie University Team : By wind tunnel study the pressure distribution on a rotor blade was measured for rotational and stationary states. The difference of the pressure distribution between the rotational and stationary conditions becomes large in the root region of the blade.
为了促进日本的离岸风电场,存在许多技术问题,例如对海岸附近风的潜力和不稳定性的预测,适合高速风力涡轮机的架空形状的形状,噪音的预测等。该研究项目是为了获得三个不同大学的团队的基本数据,以获取离岸风电场设计和开发的基本数据。每个团队的结果总结如下:Nagoya大学团队:在现场进行了风测量,以阐明风流在复杂的地形上的湍流特性,并根据风力波动的功率谱和空间连贯性评估了斜率对湍流的影响。随着斜率陡度的增加,湍流强度变得更大,并且波动在高频范围内表现出更高的水平。Tokyo大学团队:使用大型涡流和直接噪声模拟,计算了风力涡轮机叶片周围的流量和声场,并预测了在实际的旋转型号的旋转型号的旋转型号。和固定状态。旋转条件和固定条件之间的压力分布的差异在刀片的根部区域变得很大。
