WAVE AMPLIFICATIONS IN A WATER CHAMBER BEHIND VERTICAL-TYPE DISSIPATERS FOR WAVE POWER EXTRACTIONS AND RESULTANT WAVE DISSIPATION EFFECTS

Abstract

 In this study, assuming an OWC type wave power plant, wave amplification characteristics in a water chamber installed behind vertical-type dissipater units of permeable type have been studied from both experimental and theoretical points of view. The dissipation effect of reflection waves is also examined simultaneously. It was clarified that the water chamber installed behind the vertical-type dissipater units is very effective for reducing reflected waves and further exciting pumping mode wave resonances in it. The governing parameter that controls both the reflection wave dissipations and the wave amplifications in the water chamber was also studied and clarified.
