近年来，随着风能的发展，风力发电机组的规模越来越大。因此，风力机叶片变形对其性能和寿命的影响越来越明显。为了快速解决这一问题，提出了一种新的弹性驱动器线模型(EALM)，该模型基于OpenFOAM中的TurbinesFoam(OpenFOAM是一个免费、开源的计算流体动力学(CFD)软件包，由OpenFOAM基金会发布，在英格兰和威尔士注册为担保有限公司)。该模型结合了执行机构线模型(ALM)和用于风力机叶片设计的波束求解器。研究了NREL(国家可再生能源实验室)5 MW风力机的气动弹性性能，包括功率、推力和叶尖位移。将这些结果与一些研究结果进行了比较，以证明新模型的正确性。此外，还讨论了叶片变形对气动性能的影响。结果表明，塔体阴影效应越明显，功率和推力越小，越不稳定。最后，对上游风力机尾迹的这种变化进行了分析，发现对下游风力机性能和尾迹流场的影响更加严重。
The scale of a wind turbine is getting larger with the development of wind energy recently. Therefore, the effect of the wind turbine blades deformation on its performances and lifespan has become obvious. In order to solve this research rapidly, a new elastic actuator line model (EALM) is proposed in this study, which is based on turbinesFoam in OpenFOAM (Open Source Field Operation and Manipulation, a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation, which was incorporated as a company limited by guarantee in England and Wales). The model combines the actuator line model (ALM) and a beam solver, which is used in the wind turbine blade design. The aeroelastic performances of the NREL (National Renewable Energy Laboratory) 5 MW wind turbine like power, thrust, and blade tip displacement are investigated. These results are compared with some research to prove the new model. Additionally, the influence caused by blade deflections on the aerodynamic performance is discussed. It is demonstrated that the tower shadow effect becomes more obvious and causes the power and thrust to get a bit lower and unsteady. Finally, this variety is analyzed in the wake of upstream wind turbine and it is found that the influence on the performance and wake flow field of downstream wind turbine becomes more serious.
