本文给出了一台商用风力机在复杂平坦地形下的多种来流条件下的各种分离涡模拟结果。描述了复杂地形下风力机啮合过程中面临的挑战，并提出了克服这些挑战的方法。评估的主要焦点是叶片载荷和功率对入流湍流和地形影响的响应，例如倾角的变化或由于山丘而产生的加速。为了分离不同的影响，模拟设置的复杂性逐步增加。从平坦地形和均匀来流下的基线模拟开始，在复杂地形上加入大气湍流，模拟了全啮合旋转三维风力机在大气来流下的情况。
This article presents various detached eddy simulation (DES) results of a commercial wind turbine under multiple inflow conditions in complex and flat terrain. Challenges regarding the meshing process of wind turbines in complex terrain are described and an approach to overcome those is presented. The main focus of the evaluation is blade load and power response to inflow turbulence and terrain effects, e.g. the change of the inclination angle or the speed-up due to a hill. To separate the different influences, the complexity of the simulation setup is increased stepwise. Starting with a baseline simulation in flat terrain and uniform inflow over adding atmospheric turbulence to a complex terrain simulation of a fully meshed rotating 3D wind turbine under atmospheric inflow.
