Abstract EN
A concept of energy harvesting from vortex-induced vibrations of a rigid circular cylinder with two piezoelectric beams attached is investigated.
The variations of the power levels with the free stream velocity are determined.
A mathematical approach including the coupled cylinder motion and harvested voltage is presented.
The effects of the load resistance, piezoelectric materials, and circuit combined on the natural frequency and damping of the vibratory system are determined by performing a linear analysis.
The dynamic response of the cylinder and harvested energy are investigated.
The results show that the harvested level in SS and SP&PS modes is the same with different values of load resistance.
For four different system parameters, the results show that the bigger size of cylinder with PZT beams can obtain the higher harvested power.
