Optimization of rotor structure of wind energy harvester using Karman vortex street
摘要
Abstract
A wind energy harvester which can transform the kinetic energy of Karman vortex street into electricity based on electromagnetic induction principle is designed.An optimization process of the structure of the rotor is then conducted.The movement of rotor with different structures is studied numerically using Fluent.The Reynolds is 200 so as to make sure that the Karman vortex street is developed and that the flow remains 2-D.Two parameters are varied for investigation,the distance between rotor and bluff body and the length of rotor.It is found that there are three different patterns of rotor movement,vibration,rotation and mixed movement.There is a strong interaction between the two parameters.So the analysis of the two parameters can't be independent.When the distance between rotor and bluff body is 3.5 times of the characteristic length of bluff body and the length of rotor is 1.25 times of the characteristic length of bluff body,the equipment has the best output.关键词
