Sustainability | Free Full-Text | Analysis of the Patent of a Protective Cover for Vertical-Axis Wind Turbines (VAWTs): Simulations of Wind Flow


This paper presents a numerical and experimental evaluation of the patent of a tool for use in vertical-axis wind generators (VAWTs) underneath excessive wind circumstances. The machine consists of two hemispheres interconnected by a set of conveniently applied variable part ducts via which the wind circulates to the blades. Moreover, the design of the cross-section of the ducts permits the management of the wind pace contained in the machine. These ducts are supposed to work as diffusers or nozzles, relying on the wants of the set up website. Simulations had been carried out for the case of high-speed exterior wind, for which the ducts act as diffusers to cut back wind pace and preserve a well-functioning inside turbine. 4 completely different patent designs had been analyzed, specializing in turbine efficiency and generated energy. The outcomes point out that the patent permits the technology of electrical energy for a larger vary of wind speeds than with a traditional wind turbine. The outcomes help that this patent could also be a great various for wind energy technology in geographic areas with excessive climate circumstances or with maintained or robust gusty wind. Experimental exams had been carried out on the motion of the blades utilizing the out there mannequin. Lastly, the ability curve of the mannequin of this wind turbine was obtained.
