基于CFD模型风能资源模拟应用进展

Progress of application of CFD simulation for wind energy resource

中国风能资源丰富,新增装机容量和总装机容量均位列世界第一,但风能资源预测研究相对落后,本文对风能资源预测中的流体力学应用进行了综述和探讨。计算流体动力学(Computation Fluid Dynamics,CFD)是风能资源模拟的重要应用领域,本文以CFD在风能资源模拟研究方面的内容、研究方式和研究模型为出发点,从复杂地形三维建模、网格生成、计算模型选取、边界条件设定和流场模拟等方面归纳了基于CFD模型中国风能资源分布模拟研究的现状及其发展趋势。

Wind energy resources are very rich in China,and the new additions in wind capacity and the entire installed capacity in China ranks the top of the world. However, the study on prediction of wind energy resource lags behind relatively. This article reviews and discusses the application of computational fluid dynamics（ CFD） for wind resource prediction. CFD is an important application field of the simulation of wind energy resources. We start with an introduction of the CFD simulation on wind energy resources in aspects of research content,method and model. We then summarize the current status and development trend of CFD simulation on the distribution of wind energy resources in China, including the 3D modeling of complex terrain,mesh generation, selection of calculation models,boundary condition setting,and flow field simulation.
