Comparison Of Hybrid Multi-Dimensional Models Of A Bi-Stable Load-Switched Supersonic Fluidic Oscillator Application, Lovepreet Singh Sidhu
Electronic Theses and Dissertations
Fluidic oscillators are devices capable of superimposing large pressure and velocity fluctuations on the flow through a device without the necessity of having any moving parts. The lack of moving parts makes these devices superior to conventional moving-part valves in high temperature applications. The specific application of interest in the current study is the super-plastic forming (SPF) process in which large sheets of aluminum at very high temperature are formed into the desired shape by pressurizing one side inside the SPF chamber. It is known that the introduction of pressure fluctuations onto the increasing pressure in the SPF chamber reduces …
Energy Harvesting From Natural Water Flow, Haonan Kong
Energy Harvesting From Natural Water Flow, Haonan Kong
Electronic Theses and Dissertations
The hydrokinetic energy contained in flowing water is plentiful and has the potential to be one of the environmentally friendly renewable sources of energy that can be harvested. A new energy harvesting system utilizing Vortex-induced Vibration (VIV) is presented and analysed in this thesis. The proposed energy harvester generates power by direct conversion of the hydrokinetic energy of water flow into mechanical vibrations. The harvester experiences alternating fluid forces due to the repeatable pattern of alternating vortices shed from the sides of the body which generates a wake with Von Kármán Vortex Street. The proposed harvester consists of two coupled …
