Abstract: Currently the fossil fuel reserves have been depleted rapidly, and hence a sustainable energy resource is being sought in order to cover the energy demand globally. Vortex Induced Vibration (VIV) is one type of clean energy, which is a new concept in the power generating system. This concept could be used to generate kinetic power from fluid flows in oceans, rivers and stream. Hydrokinetic energy, for instance, from the flow of water is ubiquitous worldwide in the form of waves, currents, and tides; therefore it is easy and viable to get a clean energy. This report will discuss the development and investigation of Flow Induced Vibration Converter (FIVC) to extract energy from a certain range of flow by employing vortex shedding over bluff body. The experiment was conducted in the water tunnel laboratory in NTU (Nanyang Technological University). There were three design phases in this project. In the first phase, the writer designed and developed rough idea of FIVC prototype. Subsequently, in the second phase the author conducted several trials for the device and adjusting some parts until the FIVC efficiently worked. In the third phase, the finalized design was observed carefully for certain flow range (0 – 0.6m/s) to understand the characteristic of FIVC. And then, the data regarding the amplitude, power and frequency were recorded. By making use of the experimental result, the writer designed a theoretical device for real energy harvesting. And lastly, the writer also discussed on the future recommendations in contemplation of improving the FIVC efficiency.
