摘要
以浓缩风能装置为研究对象,设计6种带有不同增压板结构的改进模型。通过数值模拟和实验研究的方法,在具有风切变来流条件下对改进模型的流场性能特性进行仿真分析和试验验证。结果表明:带有增压板的浓缩风能装置具有更好的聚风加速和减轻风切变作用,其中改进模型Ⅲ的聚风加速作用较好,改进模型Ⅳ的减轻风切变作用较好;综合分析聚风加速和减轻风切变效果,改进模型Ⅵ是6种改进模型中流场性能较佳的浓缩风能装置结构。
By means of numerical simulation and experiment study, the internal flow field characteristics of six improved models in shear were simulated, analyzed and verified with the concentrated wind energy device as the research object. The results showed that the concentrated wind energy device with pressurization board can accelerate wind velocity and reduce the wind shear more efficiently. Besides the improved model Ⅲ has better efficiency of acceleration and IV has better effect on reducing the wind shear. When the efficiency of acceleration and reducing the wind shear are considered together, the improved model Ⅵ is the optimal structure of concentrated wind energy device.
