2510 空気タービン型波浪エネルギー変換システムの浮体特性と最適形状(S47-1 自然の流体エネルギー利用技術(波力,潮流),S47 自然の流体エネルギー利用技術)  [in Japanese] 2510 Characteristics and Optimal Profile of Floating Vessel for Wave Energy Converter with Air Turbine  [in Japanese]

A floating type wave power generating system has an Oscillating Water Column (OWC). The device captures the wave energy using the heaving, pitching and surging motion of the device and the heaving motion of OWC. The investigations are motivated by the experiments and the numerical analyses to find another possibility different from OWC type floating device, e.g. Mighty Whale of Japan Marine Science and Technology Center. The numerical method for analyzing a floating body with OWC type wave energy conversion device is introduced where the eigenfunction expansion method is described under the condition that the linear water wave theory is applicable. The optimal profiles are eliminated according to the different conditions from the high efficiency, i.e. the minimum size per a unit power and so on.
