- 中文摘要: 本文提供在有限水深中突出柱狀形結構物波浪繞射之邊界元素解法。文中討論了直接與間接邊界元素兩種方法,並利用較準確的直接法來計算相鄰結構物間之繞射干擾現象。比較本文結果與理論解、波源分配解、有限元素解等,相當吻合。此直接邊界元素法提供了另一計算繞射干擾現象之方法,尤其在結構物間距較大之情況下,此計算方法更為經濟有效。
- 英文摘要: Numerical calculation procedures are presented for computing the wave diffraction by surface-piercing structures in an ocean of finite depth by the Boundary Element Method. Both direct and indirectboundary elements have been investigated. The more accurate direct formulation is used to calculate thewave interference effects on multiple structures. Comparisons between the present results and resultsavailable from analytical, source distribution and finite element methods are good. Therefore, this directBoundary Element Method provides an alternative calculation procedure for multiple wave interferenceanalysis, especially when the structures are at some distance apart.
