| 摘 要： | 五体船是继当代三体船之后提出的又一种多体新船型,该新船型付诸实用前必须对其兴波特性和侧体布局减阻设计进行研究。根据五体船各片体的科钦函数线性叠加和坐标变换原理,提出了基于片体科钦函数展开的分项算法和基于片体科钦函数叠加的整体算法求解多体船兴波阻力,得出了单体船、三体船、五体船通用的线性兴波阻力公式。应用CFD通用软件进一步分析五体船阻力及片体兴波干扰特性,提出了基于CFD模拟的自由面波形观测的五体船片体布局优化,对各种侧体布局下的五体船兴波特性直观地定性判定。根据综合兴波阻力线性理论计算和粘性流体动力CFD求解所得五体船阻力结果及其特性,提出具有工程实用意义的五体船优化构型方案。研究表明,势流线性理论计算和CFD求解五体船阻力的方法和所得五体船优化构型方案具有广阔的应用前景。

| Abstract: | The pentamaran was proposed as another new concept of multihull ship form following the contemporary trimarans.The investigation on the wave resistance characteristics and resistance reducing outrigger configuration is necessary for its application.According to the Cochin function linear superposition and coordinate transformation principle of the central hull and four outriggers of pentamarans,the expanded and whole arithmetic for the Cochin function were brought forward to solve the multihull ship wave re... |
