摘要：
本文对一种用于垂直轴风力机（VAWTs）在极端风况下的装置专利进行了数值与实验分析。该装置由两个半球组成，通过一组经过合理设计的变截面管道相互连接，风通过这些管道流向叶片。此外，管道横截面的设计允许控制装置内部的风速。这些管道根据安装地点的需要，既可作为扩压器，也可作为喷嘴使用。针对外部高速风的情况进行了仿真，此时管道充当扩压器以降低风速，并维持内部风力机正常运行。分析了四种不同的专利设计，重点关注风力机性能和发电功率。结果表明，与普通风力机相比，该专利能够在更大的风速范围内产生电能。结果支持该专利可能是地理区域中具有极端天气条件或持续强阵风条件下风力发电的良好替代方案。利用现有模型对叶片运动进行了实验测试。最后，获得了该风力机模型的功率曲线。
英文摘要：
This paper presents a numerical and experimental analysis of the patent of a device to be used in vertical-axis wind turbines (VAWTs) under extreme wind conditions. The device consists of two hemispheres interconnected by a set of conveniently implemented variable section ducts through which the wind circulates to the blades. Furthermore, the design of the cross-section of the ducts allows the control of the wind speed inside the device. These ducts are intended to work as diffusers or nozzles, depending on the needs of the installation site. Simulations were performed for the case of high-speed external wind, for which the ducts act as diffusers to reduce wind speed and maintain a well-functioning internal turbine. Four different patent designs were analyzed, focusing on turbine performance and generated power. The results indicate that the patent allows the generation of electric power for a greater range of wind speeds than with a normal wind turbine. The results support that this patent may be a good alternative for wind power generation in geographic areas with extreme weather conditions or with maintained or strong gusty wind. Experimental tests were carried out on the movement of the blades using the available model. Finally, the power curve of the model of this wind turbine was obtained.
