聚碳酸酯材料的浓缩风能装置流固耦合分析

浓缩风能装置是浓缩风能型风力发电机的核心部分，其选材直接影响到浓缩风能型风力发电机的推广应用。该文应用流固耦合分析方法，采用CFD软件进行流场分析，对浓缩风能装置在特定风场下进行仿真模拟，得到了浓缩风能装置所处流场的风速和风压分布。将流场计算结果作为载荷加载到浓缩风能装置上，该装置在风中所受最大应力3.267 MPa，远小于拜耳makrolon 2407型聚碳酸酯的屈服应力66 MPa、断裂应力65 MPa以及弯曲强度98 MPa，因此该型号聚碳酸酯在强度上满足浓缩风能装置要求，可以替代目前所用材料冷轧钢板。该研究结果可为后期的结构改进和优化设计提供理论依据和参考。...

The concentrated wind energy device is the core of the concentrated wind energy generator, and its material can directly affect the widespread application of the concentrated wind energy generator. This research adopts a fluid-solid interaction （FSI） method. At first, a solid-field model of a concentrated wind energy device is created with the help of the CAD software according to the size of the model. And a cylindrical area is established after the solid-field model is imported into the finite element analysis software. The cylindrical area has a radius of 10 m and a length of 30 m and the distance between the inlet of the fluid-field area and the inlet of the concentrated wind energy device is 5 m. Then in the cylindrical area, a geometric fluid field is established through Boolean subtraction of the solid field area. Based on the CFD software analysis of the fluid field, the wind flow is simulated in a specific wind field. A non-uniform tetrahedron meshing and an SSTk-ω turbulence model are adopt
