Force and Motion Analysis of Blade-less Wind Energy Harvesters

This paper is focused on design of blade-less wind energy harvesters(BWEH) and computational fluid dynamic analysis of BWEH. Conventional wind turbine uses rotary machines to extract power from wind which requires high maintenance and the wake area between two wind turbines is significantly large. In contrast to conventional wind turbines, which rely on rotary mechanisms for power generation, bladeless turbines extract the energy procured from vortex-induced vibrations(VIV). Mathematical model equation are developed using dimensional analysis. Nature of lift force experienced by the BWEH, Motion of blade-less wind energy harvester is discussed in the paper.
