Design and Analysis of Bladeless Wind Turbine at Low Wind Speed
摘要
A completely novel method of harnessing wind energy is employed by bladeless wind turbines. The vortex-shedding phenomenon, an aerodynamic feature that has long troubled structural engineers and architects, it is captured using a gadget. The wind’s flow alters as it passes by a permanent object, creating a cyclical vortex pattern. When these forces get sufficiently powerful, the stationary structure begins to oscillate, may even collapse as it enters resonance with the wind’s lateral forces. The Tacoma Narrows Bridge is a well-known academic example that collapsed 3 months after it was opened due to the effects of galloping and flattering as well as the vortex-shedding effect. The goal of the Spanish SME Vortex Bladeless is to create the vortex or vorticity wind turbine, a novel idea for a wind turbine without blades. With the goal of removing or reducing many of the current issues with traditional generators, this design offers a new paradigm in wind energy.
