基于田口方法优化双Savonius风力机立体阵型
A Taguchi-based optimization on three-dimensional array configuration of dual Savonius wind turbine
摘要
Abstract
[Purposes]To address the demand for efficient wind energy utilization in low-wind-speed regions,this study took the three-dimensional array configuration of Savonius wind turbines adapted for low-wind-speed environments as its research object.It conducted a multi-parameter optimization design,aiming to enhance their overall wind energy utilization efficiency.[Methods]The three-dimensional computational fluid dynamics(CFD)simulation method was combined with the Taguchi experimental design method to systematically analyze the effects of five parameters,namely horizontal spacing,horizontal included angle,vertical spacing,rotational direction,and initial phase angle,on the average power coefficient of the dual wind turbine system.[Findings]Vertical spacing exerts the most significant regulatory effect on the system's power coefficient,followed by the rotational direction,horizontal included angle,initial phase angle,and horizontal spacing.The theoretically optimal parameter array configuration identified through multi-parameter optimization enables the system to achieve an average power coefficient of 0.177,representing a 6.5%enhancement compared to a single wind turbine.Flow field analysis reveals that the synergistic interaction between vertical spacing and the counter-rotating mode can attenuate wake interference,accelerate momentum recovery,suppress the growth of turbulent kinetic energy in the negative torque region,enhance the positive torque driving effect,and thereby improve the overall wind energy utilization efficiency.[Conclusions]The proposed three-dimensional array configuration of Savonius wind turbines enhances system stability and reduces the impact of variable wind direction on the system's power coefficient through the synergistic regulation of coupling effects between vertical spacing and other parameters.By efficiently utilizing vertical space,it significantly expands the wind-capturing area.This array configuration thus provides robust technical support for clean energy planning and power system layout in practical low-wind-speed regions.关键词
