  1. Since these theoretical analyses are based on inviscid potential flow theory, theoretical calculation and computational simulation may complement each other. the hydrodynamics and undulating propulsion of specimens were studied using three dimensional computational fluid dynamics ( cfd ) modeling. the cfd analysis using kinematic model of undulatory dorsal / median fin draws a series of conclusions, which include that the body drag increases significantly with the lateral body oscillation ; the body drag is minimum while the start point of

    計算結果表明游動過程中的形體阻力隨側向周期性擺動而增大;當背鰭前端位於身體側向最寬處時，形體阻力具有局部最小值，結論與實驗觀測結果相吻合;在實驗觀測的典型運動參數下，波動面的運動方程中的非對稱因素的出現使推進力增大約1 . 10倍。
  2. In this thesis, according to the theory of potential flow, the mathem - atical model of two bodies moving in inviscid fluid with arbitary 3 - dimensional shape is presented and the formula of interacted force between them is derived

    本文以勢流理論為基礎，根據水下兩個物體運動的數學模型，給出了它們間相互作用力的公式。
  3. Therefore this approach has become the highlight of the cfd field, and has received much attention. based on this optimization design theory, this thesis deeply studies some kinds of aerodynamic design problem in inviscid and viscous flow, such as aerodynamic inverse design and drag reduction problems. at the same time, the aerodynamic design optimization programs have been developed successfully

    基於該設計方法的研究價值和應用前景，本文通過應用控制理論的優化設計方法，對無粘性流動和粘性流動情形下不同類型的氣動設計問題進行了深入研究，如反設計、減阻問題研究，成功發展了相應的氣動外形優化設計程序。
