Design and Fabrication of Bladeless Wind Mill

Mechanical Engineering

Today, India is top amongst the list of developing countries in terms of economic development. Hence the energy requirement is increasing rapidly. To meet these energy requirements non- renewable energy sources are used excessively but due to limited storage of this sources there is a need for generation of clean energy through renewable energy sources. India is having fifth largest installed wind power capacity in the world. As the region of high speed wind is limited and also the area required for installation of conventional windmill is high, bladeless windmill based on vortex induced vibrations can provide the solution for these disadvantages of the conventional windmill. Bladeless windmill basically works on the vortex shedding effect. The device is composed of a single structural component, and given its morphological simplicity, its manufacturing, transport, storage and installation has clear advantages. The new wind turbine design has no bearings, gears, so the maintenance requirements could be drastically reduced and their lifespan is expected to be higher than traditional wind turbines. Generally structures are designed to avoid vortex induced vibrations in order to minimize the mechanical failures. But here, we try to increase the vibrations to increase the generation of electricity.
