Computations of Ship Flow Around Commercial Hull Forms with Free Surface or Propeller Effect

考慮自由液面效應或螺槳作動之商用船型周圍流場計算

摘要


本文以聯合船舶設計發展中心開發的三維黏性流計算程式為基礎,分別以兩艘商用船型為計算實例,考慮自由液面效應或螺槳作動的情形下,進行船隻周圍的流場特性計算。文中引進組合式網格技術及等效物體力模型,並耦合黏性流及螺槳勢流計算程式,藉以模擬螺槳作動時與船體間的交互作用。各項流場特性計算結果與實驗值比較有相當高的一致性,印證了此一計算方法在船型設計階段有極高的實用價值。

並列摘要


A finite volume method, based on artificial compressibility scheme, to solve the nonlinear ship wave resistance problems is presented. The equivalent body force method is adopted in a viscous/potential flow coupled scheme to evaluate the propeller-hull interaction problem. The composite grid technique is incorporated to enhance grid generation flexibility for treating complex geometry. The present results of several conditions for modem commercial hull forms have been validated by a proper comparison with experimental data. It is demonstrated that the present method can be applied to the evaluation of hull form with required accuracy for practical use.
