Testing Of A Ducted Axial Flow Tidal Turbine, Thomas A. Lokocz
Testing Of A Ducted Axial Flow Tidal Turbine, Thomas A. Lokocz
Electronic Theses and Dissertations
Energy independence and a reduction on the reliance on fossil fuels is a critical area of current research and development. Utilizing the energy in the world’s oceans can help the world move towards a more sustainable energy supply. One of the most promising sources of ocean energy is tidal energy or marine hydrokinetics, the topic of this thesis. This research analyzes the performance of a ducted axial flow tidal turbine and compares the result to an unducted turbine. While the focus of this research is on experimental results obtained in tow tank tests, the turbine and duct were designed using …
Numerical Simulation Of Natural Convection In Rectangular Enclosures Of Varying Aspect Ratios And Its Feasibility In Environmental Impact Management Studies, Charles R. Walker
Numerical Simulation Of Natural Convection In Rectangular Enclosures Of Varying Aspect Ratios And Its Feasibility In Environmental Impact Management Studies, Charles R. Walker
Electronic Theses and Dissertations
Author's abstract: Numerical simulation was used to investigate natural convection in horizontal and vertical enclosures with and without an internal heat source. Natural convection in rectangular enclosures is found in many real-world applications. Included in these applications are the energy efficient design of buildings, operation and safety of nuclear reactors, solar collector design, passive energy storage, heat transfer across multi-pane windows, thermo-electric refrigeration and heating devices, and the design-for-mitigation of optical distortion in large-scale laser systems. Considering all these applications, especially controlling heat transfer in nuclear power plants, knowledge and research results of natural convection in enclosure play a vital …
