Enhancing Self-Starting Capability and Efficiency of Hybrid Darrieus–Savonius Vertical Axis Wind Turbines with a Dual-Shaft Configuration

Machines
Self-starting capability has consistently presented a significant challenge for Darrieus vertical axis wind turbines (VAWTs). One advantageous approach to addressing this problem is the design of a hybrid Darrieus–Savonius VAWT.

A Curtain Design on Optimizing Configuration of Savonius Rotor

, 2012
以输出功率100W的阻力型垂直轴型风力机为例,通过优化设计找寻最佳的叶片数目、高径比和折叠率等几何参量,然后加入导风帘装置,给出一个最佳结构方案。运用fluEnT求解器中的有限体积法对无导风帘和三种不同长度导风帘设计的叶片周围的流场进行模拟。模拟与最佳优化方式的性能参数的计算结果表明,采用长导风帘设计的阻力型垂直轴风力机具有最好的动力学性能,可以提高运行效率。This paper mainly studies the configuration of Savonius rotor on the ...
