METHOD OF ESTIMATING THE POWER EXTRACTED BY FIXED COASTAL TYPE WAVE POWER EXTRACTORS

Abstract

Study is performed on a vertical flap type energy converter, "Pendulor System". The power absorbed with the system in random waves is estimated using a transfer function of absorbed power (absorption coefficient) in regular waves and wave spectrum. A boundary element technique is applied to compute the hydrodynamic problem associated with the system which is placed in regular waves. The applicability of the method has been examined by a series of field test at a test plant caisson. The agreement between estimation and experiment was found to be good except near the resonance frequency of the system.
