摘　　要：针对垂直轴风力机风能利用率略低于水平轴风力机的问题,提出一种基于塞内加尔(Senegal)型风机的新型风力机。首先,利用贝塞尔曲线函数对转子叶片的弧度进行优化,并利用SOLIDWORKS软件进行建模,得出4种不同弧度曲线的叶片;其次,利用计算流体动力学(CFD)模型分别对不同叶尖速比(TSR)下的风能利用率、力矩系数等参数,以及风力机的压力分布图和速度分布图等图表进行对比分析,同时对比其尾流特性;最后,搭建实验平台验证仿真模拟实验的合理性。结果表明,优化叶型有效提高了改良Senegal阻力型垂直轴风力机的风能利用率,A4型叶片具有较高的风能利用率,达到26.31%,相较于A1型风力机提高了约36%。所设计的新型风力机结构具有优越的发电性能,可为垂直轴风力发电机领域的方案设计提供参考。Aiming at the problem that the wind energy utilization of vertical axis wind turbines is slightly lower than that of horizontal axis wind power,a new wind turbine based on Senegalese(Senegal)type wind turbine was proposed.Firstly,the curvature of the rotor blades was optimized using the Bessel curve function and modeled using the SOLIDWORKS software,resulting in four different curvature curves for the blades;Secondly,the parameters such as wind energy utilization,moment coefficient,and their pressure distribution and velocity distribution plots at different tip speed ratios were compared and analyzed using computational fluid dynamics(CFD)model,and their wake characteristics were also compared;Finally,an experimental platform was built to verify the rationality of the simulation.The results show that the optimized blade type effectively improves the wind energy utilization of the modified Senegal drag type vertical axis wind turbine,and the A4 type blade has a high wind energy utilization of 26.31%,which is about 36%higher than that of the A1 type wind turbine.The designed novel wind turbine structure has superior power generation performance,which provides some reference for program design in the field of vertical axis wind turbines.
