著者：押川 英夫; 小松 利光題名：振動流場における非対称没水構造物周りの流動解析発表情報：水工学論文集 巻: 50 ページ: 817-822キーワード：概要：Characteristics of an oscillatory flow around submerged asymmetrical structures (we call this structure the BaNK block) were investigated on the basis of numerical simulations. Komatsu et al. have proposed 'BaNK System' in order to cope with beach erosion and shoaling of fairway. In this study, a half cylinder is used as the BaNK block which is set on the bottom of an oscillatory flow channel. It was found that a residual hydrodynamic force increases as Reynolds number becomes larger. Furthermore, residual currents due to asymmetrical structures were comprehended by analyzing simultaneous flow patterns with different phases.抄録：英語フィールド
