| 摘 要： | 采用UDF(User-Defined Function)和动网格相结合的方法对链传动式风力机三维流场进行数值模拟研究.通过对不同风速下4种叶轮的压力场、速度场以及风能利用系数的分析计算,发现叶片在流场中的形态对叶片的受力有较大的影响,风力机前后层叶片间的流场均匀地分布会有效提高后层叶片对风能的利用率.

| Abstract: | Three-dimensional flow field of chain-drive wind turbine was numerical simulated by UDF(User-Defined Function) and dynamic meshing.Through the calculation and analysis for the stress field,velocity field and wind power utilization coefficient on four kinds impellers at different wind speed,the result showed the morphology of blades in flow field has a greater effect on the stress of blades,the uniformity of the flow field from beginning to end in the layer of impeller could improve the effective availabilit... |
