由于日本有很大一部分地形陡峭复杂，导致风速的空间分布复杂，因此在选择风力发电机（WTG）的建设地点时需要非常小心。我们已经开发了一个名为RIAM‐COMPACT的非定常流场CFD模型（九州大学应用力学研究所，复杂地形上气流的计算预测）。RIAM - COMPACT CFD模型基于大涡模拟（LES）。RIAM‐COMPACT的计算范围可以从几米延伸到几公里，并且RIAM‐COMPACT可以高精度地预测复杂地形上的气流和气体扩散。本文提出了一种评估WTG部署位置的技术。该技术采用RIAM‐COMPACT CFD模型，模拟了360度的连续风向变化。
Because a significant portion of the topography in Japan is characterized by steep, complex terrain, which results in a complex spatial distribution of wind speed, great care is necessary for selecting a site for the construction of wind turbine generators (WTG). We have developed a CFD model for unsteady flow called RIAM‐COMPACT (Research Institute for Applied Mechanics, Kyushu University, computational prediction of airflow over complex terrain). The RIAM‐COMPACT CFD model is based on large eddy simulation (LES). The computational domain of RIAM‐COMPACT can extend from several meters to several kilometers, and RIAM‐COMPACT can predict airflow and gas diffusion over complex terrain with high accuracy. The present paper proposes a technique for evaluating the deployment location of a WTG. The proposed technique employs the RIAM‐COMPACT CFD model and simulates a continuous wind direction change over 360 degrees.
