Description
本発明は、2006年5月1日に出願されたWave Energy Converter(WEC) with Heave Platesの仮出願第60/796,388号から優先権を主張し、当該仮出願の内容は参照により本明細書に援用される。
FInterial=(CmVequivalentρ)a=AddedMass×a(式1)
であり、式中、Cmは実験的に決定された因子であり、Vequivalentは上記で定義した等価体積であり、ρは水の密度であり、aは加速度である。なお、質量の単位を用いる付加質量項は、括弧内の変数の組み合わせであることに留意されたい。
VLippedPlate=4/3 π(D/2)3×(1+3/2 h/D)(式2)
によって表され、式中、Dは板の直径であり、hはリップの全高である。式2は、鉛直構造S1、S2を有する円形板で巻き込まれる水体積が、プレーンな板(すなわち、鉛直構造を有しない)の移動によって形成される水の球の体積+板の面積と鉛直構造(リップ)の高さとによって形成される水の円柱の体積であることを示す。上記の式1と関連して述べたように、実験的に決定された因子に上記値及び水の密度を掛けると、付加質量値が得られる。
δMinimumDiameterIncrease=(1+3/2 h/D)1/3(式3)
だけ大きくならなければならない。
