摘要
对风力机在不同运行工况下的功率变化进行了研究,首先使用三维建模CATIA软件对风力机进行了建模.之后,将所建立的模型进行网格划分,导入到FLUENT流体仿真软件中,使用FLUENT软件进行仿真计算,得出风力机的应力云图、风速云图和矢量图.根据计算公式与FLUENT软件数据相结合方法,得出在不同转速下风力机功率的变化曲线.得出结论,在风速不变的运行工况下,所建立风力机的功率随着转速的增大而逐渐增大.
Abstract
The power changes of wind turbines under different operating conditions are studied.First,the wind turbines are modeled using 3D modeling software CATIA.After that,the established model was meshed and imported into FLUENT fluid simulation software.FLUENT software was used to carry out simulation calculations to obtain the stress nephogram,wind speed nephogram and vector graph of the wind turbine.According to the combination of calculation formulas and FLUENT software data,the change curve of wind turbine power at different rotational speeds is obtained.It is concluded that under the operating condition with constant wind speed,the power of the established wind turbine will gradu-ally increase with the increase of speed.
