摘　　要：为提高浓缩风能型风电机组的输出功率,以增压圆弧板及其迎风角为研究对象,对浓缩风能装置内部流场进行仿真分析,并通过车载实验和风洞实验数据验证数值模拟结果的可靠性。结果表明,增压圆弧板可有效提高浓缩风能效率;综合考虑制造成本、流场特性和风切变等因素,增压板迎风角为60°的浓缩风能装置模型流场特性较佳,最大流速是来流风速的2.36倍。To improve the output power of concentrated wind energy turbine,the internal flow field of concentrated wingenergy device is simulated and analyzed with the pressurization board and its windward angle as research object.Truckmounted experiment and wind tunnel experiment are carried out to verify the reliability of numerical simulation.Theresults showed that the pressurization board can effectively improve concentration efficiency.Considering the factors suchas manufacturing cost,flow field characteristics and wind shear,the structure with pressurization board windward angleof 60° is the optimal model of concentrated wind energy device,and the maximum flow velocity is 2.363 times of theinflow velocity.
