| 摘 要： | 能够以一定偏角(船舶纵轴线与航行轨迹切线间的夹角)斜向航行的非对称船型,是国外近年提出的一种新船型,在多种海洋工程作业中有着得天独厚的优势,具有广阔的应用前景。本文通过数值模拟和船模实验方法对一型非对称船型的不同航向的阻力性能进行了研究,计算了其不同斜向航行偏角下的阻力,以获得阻力系数随斜向航行偏角变化的关系,并依据计算结果得到斜向航行角度大于30°时,船体迎流段对黏压阻力的影响将超过去流段的结论,为今后该类船舶的设计提供参考。

| Abstract: | The asymmetric hull which can sail sideways at a certain deflection-the angle between the longitudinal axis of a ship and the tangent of the path of the voyage,hasSbroad prospects onSmany types of offshore engineering applications. The resistance performance of a type of asymmetric hull is studied by numerical simulation and ship model experiment , and the resistance at different oblique navigational deflection is calculated to obtain the relationship between the resistance coefficient and the oblique navigation deflections. The result shows that the entrance has more influence on the viscous pressure resistance compared with the run when the oblique navigational deflection is greater than 30°,providing a reference for the design of this kind of ship in the future. |
