摘要
应用基于Betz理论的工程算法设计了600W和2kW的水平轴风力机,并采用CFD软件Fluent对风力机叶轮的流场进行了数值模拟,得到的风力机功率与风洞试验结果吻合良好,说明LES湍流模型和自适应网格在小型水平轴风力机的数值模拟中的精确度较高。数值模拟同时显示了风力机流场的压力分布,对叶片的流动分离进行了分析讨论。
A 600W and 2kW horizontal axial wind turbine are designed based on the engineering algorithm Betz. The numerical simulation of flow filed for wind turbine rotor is made by using Fluent. The calculated wind turbine power compares well with the experimental data, and the influences of LES and adaptive mesh on numerical simulation results are also studied. The results of pressure distribution and separation flow-field around the blade section are simulated.
