VORTEX INDUCED VIBRATION ENERGY EXTRACTION DEVICE WITH ELLIPSOIDAL CROSS SECTION CYLINDER

摘要

PURPOSE: An extraction device for vortex induced vibration energy with an ellipsoidal cross section cylinder is provided to provide a vortex generation cylinder which is formed in an optimal aspect ratio of a cross section for obtaining improved energy extraction efficiency through hydrostatic analysis. CONSTITUTION: An extraction device for vortex induced vibration energy with an ellipsoidal cross section cylinder comprises a vortex generation cylinder(100), an energy transmission device(200), and a power generation device(300). The vortex generation cylinder vertically vibrates by generating a vortex on the surface by the vortex exfoliation due to the flow of fluid. The aspect ratio of the ellipsoidal cross section is 0.3-0.5. The energy transmission device transmits kinetic energy of a vortex vibration which is generated in the vortex generation cylinder. The power generation device converts the kinetic energy of the vortex vibration which is transmitted through the energy transmission device to electric power. The cross section of the vortex generation cylinder has an ellipsoidal shape. The power generation device converts kinetic energy of a linear reciprocating which is transmitted due to the vortex vibration generated by the vortex generation cylinder to electric energy. The energy transmission device connects the power generating device with the vortex generation cylinder and transmits linear reciprocating kinetic energy to the power generation device which is generated by the vortex vibration of the vortex generation cylinder.
