• 中文摘要： 本文提出了一種小板法來推導潛體在自由液面下運動之興波阻力。在推導過程中，出現在勢流格林函數中之雙重積分項以一具有複數指數積分型式之單積分來取代。利用此種方式，使得數值計算方法變得可行，因此可延伸來計算潛體之興波阻力。在本文中，小板上之源點強度利用高斯消去法配合部份樞軸法可有效解出。文中亦發現利用本方法及適當之網格分佈即可得到令人滿意之結果。此結果與別的理論方法以及實驗數據相比較，皆相當吻合。因此本文所提供之方法亦可作為一分析潛體興波阻力之工具，而且對於其它有關的潛航器設計亦非常有用。
• 英文摘要： This paper presents a panel method to evaluate the wave resistance on a submerged body movingbeneath a free surface．In the process of evaluation, the double integral term in the potential functionis replaced by a single integral with the integrand expressed in terms of the complex exponential integral．With such derivation, the numerical computing techniques become available and can then be extendedto calculate the wave resistance on a submerged body. Here the sets of the source strength on the panelsare solved efficiently by applying the Gaussian elimination method incorporated with the partial pivotingtechnique. It is found that use of these techniques incorporated with a suitable body mesh distributioncan lead to satisfactory results which agree with those obtained using other methods and experimentaldata. The present paper offers another tool to solve the wave resistance of a submerged body movingbeneath a free surface, which is very useful for the design of certain underwater vehicles
