In this thesis, a device by applying the oscillating water column in a well-like resonant chamber installed in a floating structural system is studied experimentally. The device was designed to utilize the oscillation motion of the water inside the resonant chamber and then the pressure variation of the air to drive the air-turbine system. When connected to a electric power generation system this device may convert the wave power to electric power.
A theory assuming independence between the motion of floating structure and the heave of waves inside the resonant chamber, derived by McCormick (1976 ) is adopted in this study. During the experimental tests four groups of test were carried out depending on the parameters that are to be evaluated for the effectiveness of the power conversion, namely, the rotation speed of the turbine with or without the power generator attached, the relative wave-height variation between the incident wave and waves in the well-like resonance chamber and the actually generated electric potential. For each group of test five sets of wave-height from 6 cm to 10 cm and four sets of period of wave, namely, 0.89, 0.92, 1.06, 1.20-second are applied.
