Aeroelastic analysis of a wind belt energy harvester

Abstract EN

Wind belt technology is a method of energy harvesting that converts wind energy into mechanical energy, and then into electrical energy.

The wind belt relies on an aerodynamic phenomenon known as aeroelastic flutter.

The wind belt uses a tensioned belt undergoing flutter to extract energy from the wind and pair of magnets are attached to belt are coupled with fixed electric coils.

The flutter of belt causes a change in the strength of the magnetic field applied to the electric coil, thus generating electricity.

The objective of this paper is analyze of wind belt motion which is coupled between transverse and rotational motion to estimate flutter speed and natural frequencies.

Developed wind belt device produce power about 1 mW DC at wind speed 3 m/s.
