    Abstract: 本論文主要是利用The DELTA Method (The Desingularized Eulerian-LagrangianTime-domainApproach method)為數值基礎,以簡單的直壁型浮體模擬浮體在激烈運動時產生的波浪翻轉(wave overturn )現象。本文的特點為將已發展的DELTA 方法改良其對於自由液面節、源點的佈置方式,改採用新的節、源點佈置方式,因此對於自由液面上的節點不會因為波浪的劇烈運動,而產生交錯重疊的情形,在改良自由液面的佈點方式之後,如此便可用來模擬自由液面因激烈高速運動而產生的波浪翻轉(wave overturn )的現象。最後本文利用DELTA 方法所獲得之數值計算結果以及分析模擬的結果將在本文呈現以及討論。
    The numerical model developed in this work takes DELTA method (Desingularized Eulerian-Lagrangian Time-domain Approach method) as its theoretical basis. "Desingualrized" means to move the singularities that traditionally located right on the boundaries of the computational domain out of the domain, hence, the special treatment for the singularities is avoided. The boundary conditions applied in the time-domain numerical model built in this paper are fully nonlinear kinematic and dynamic free surface boundary conditions, and exact body boundary condition. The variations of free surface are simulated when different types of floating bodies are moving with forced motions. Finally the numerical results obtained using DELTA method are presented and discussed in this paper.
