摘要：In order to make the bladeless wind turbine better convert wind energy into electric energy, this paper based on the method of passively controlling vortex-induced vibration, by changing the shape of the cylindrical surface, selecting three different parameters of the wavy cylinder (λ/Dm=6, ɑ/Dm=0.15; λ/Dm=2, ɑ/Dm=0.15, λ/Dm=2, ɑ/Dm=0.3), and performing a numerical simulation at Re=100. The results show that the wavy cylinder of λ/Dm=2, ɑ/Dm=0.15 is more susceptible to induced vibration. Compared to straight cylinders, the wavy cylinder of λ/Dm=2, ɑ/Dm=0.15 have a wider range of lock-in and a larger amplitude.
