致动线模型利用旋转的线表示叶片,利用二维翼型气动数据根据BEM理论计算叶素点作用力,同时通过求解N-S方程计算转子流场。本文首先基于商业CFD软件ANSYS FLUENT开发了致动线模型,并计算了切变入流风况下风力机的气动和尾流特性,发现由于地面阻碍和风切变效应导致风力机尾流存在明显的非对称特征。 Actuating line model uses the rotating line to represent the blade, and uses the two-dimensional airfoil aerodynamic data to calculate the force of the leaf element according to the BEM theory. At the same time, the rotor flow field is calculated by solving the N-S equation. In this paper, based on the commercial CFD software ANSYS FLUENT, the actuator model was developed and the aerodynamic and wake characteristics of the wind turbine under shear flow were calculated. It is found that there is a significant non-existence of wind turbine wake due to ground obstruction and wind shear effect Symmetrical features.
