本論文採用三維勢流理論並利用源點分佈法之技巧來分析雙體船在規則波中以等速航行所受之穩態與非穩態流體動力問題。
首先利用小板法將船體浸水表面劃分成許多四角形小板,在四角形小板上分佈三維平移型源點與脈動型源點求解源流強度及壓力分佈,進而求得穩態興波問題與非穩態之船體運動問題,以及兩者之間的耦合影響。
本篇對於截尾船型之處理亦作了深入的研究,對於雙體船之分析提供有用的分析模式。
In the paper, the steady and unsteady hydrodynamic problems of SWATH moving in regular waves are analyzed by using a three-dimensional potential theory and the source distribution technique.
At first, let the mean wetted hull surface area be represented by source quadrilateral elements, and the source intensity and pressure distributions can be solved. Finally the steady exciting wave resistance and unsteady ship motion problems to obtain. The effects of resonance between them also included.
In this paper, we focus on the transom of ship, The analytic models here developed are useful to predict the characteristic of SWATH.
