Geometric Optimization Of A Heaving Point Absorber Wave Energy Converter, Ian Riley
Geometric Optimization Of A Heaving Point Absorber Wave Energy Converter, Ian Riley
Electronic Theses and Dissertations
Wave energy shows significant potential for development into a competitive renewable energy source. Non-renewable resources are finite and contribute to adverse effects on the environment. Development of wave energy conversion devices that use heave motion as the primary driver for converting wave energy into electrical potential is explored through optimizing the geometry of an axisymmetric partially submerged buoy in deep water. The governing equations of motion and hydrodynamic forces are solved for in one degree of freedom using ANSYS Aqwa. An external PTO device is simulated to induce power capture in the system. Four different geometric shapes are tested and …
