Abstract:
There is a need for renewable energy sources to be more feasible. The purpose of this project is to develop a compact device that is able to harvest wind energy and transform it into electrical energy using the concept of vortex shedding. When calibrated correctly, the vortex shedding will induce resonant oscillation. Electricity would be collected from this oscillation using a magnet and coil assembly. This method was proven to work in water, but has not been applied to air currents. Our group designed and built a small-scale prototype to be tested in closed circuit wind tunnel. The wind harvester works at a moderate wind range of 3 to 5 m/s. Data was collected on the amplitude and frequency of motion of the flutter plate during its lock-in condition. Calculations were done to find position, velocity, and acceleration of the system over a complete cycle. The results demonstrate a potential for vortex induced vibration to be utilized with wind to create electricity, however it will be difficult due to the low density of air compared to other fluid mediums, such as water
