外文摘要：Improving the performance of Vertical Axis Wind Turbine(VAWT)is one of the current research hotspots in the wind energy field. To address the poor startup performance and low aerodynamic efficiency of Darrieus VAWT, this paper proposes a novel triple-layer airfoil Darrieus VAWT (TD-VAWT). Building on the design where auxiliary blade A is already mounted on the same blade support arm as the main blade, auxiliary blade B is added to a different blade support arm. The overall performance of the VAWT is improved by adjusting auxiliary blade B relative orientation with respect to the main blade. A wind tunnel was established to investigate the effects of various structural parameters on TD-VAWT performance. The test results indicate that the optimal parameter combination is a 30 degrees angle between auxiliary blade B and the main blade, with a radial distance of 161.5 mm when the tip speed ratio (TSR) is below 0.8. The configuration improves startup performance by a factor of 1.8 and increases aerodynamic performance by 18.8% compared to a VAWT equipped with only blade A. This study indicates that adding auxiliary blade B can effectively improve wind energy utilization efficiency under conditions of low TSRs, providing experimental support for the structural optimization of Darrieus VAWT.
