| Summary: | 碩士 === 國立臺灣海洋大學 === 系統工程暨造船學系 === 106 === In Taiwan, the development of Kuroshio Energy is an important issue. At present, Taiwan has developed ocean current turbines. How to make ocean current turbines operate stably under water in the harsh environment around Taiwan is the core technology of ocean current energy development. In this study, the Floating Kuroshio Turbine system which developed by National Taiwan University and National Taiwan Ocean University is used as a model to explore the dynamic balance and motion state of the unit under different anchor chain systems.
Several commercial software-assisted calculations were used in this study, the system drag coefficient was calculated by ANSYS FLUENT; the system hydrodynamic coefficient was calculated using WAMIT; the system dynamics and cable tension were calculated using OrcaFlex, and other relevant parameters, such as turbine thrust And system lift is obtained from specific programs and experimental data.
In this study, the dynamic balance and motion state of Floating Kuroshio Turbine system under different anchor chain systems are discussed. According to the simulation results, the thickness of the cable has a significant impact on the stability of the system. If the diameter of the cable is less than a certain value, the system will be Unstable. Systems with different numbers of secondary cables have different system motions, even natural frequencies. The form of the cable is also an important factor in the motion of the system.
