薄船的孤立子生成特性及其几何参数关系的研究

INVESTIGATION ON THE RELATION BETWEEN GEOMETRICAL PARAMETERS OF A SLENDER SHIP AND SOLITON-RADIATION CHARACTERISTICS

本文用实验和数值计算的方法探讨了薄船在有限宽的浅水池中以跨临界速度运动时向前辐射出的孤立子的规律,发现孤立子生成特性对船型的依赖关系是非常复杂的,并不仅限于所提出的“堵塞系数”这一个参数,船头型线与中心线的夹角和船身长度亦是和堵塞系数同量阶的控制参数。

The solitons radiated by an impulsively started slender ship advancing near critical speed in a shallow water channel with finite width are investigated. For studying the dominant parameters which govern the sollton-radiation characteristics, numerical calculation and experimental method were used.It is found that the relation between geometrical parameters of a slender ship and the soliton-radiation characteristics is very complex. The Soliton-radiation Characteristics for slender ship depend, on not only the so called blockage cofficient suggested by Ertekin, but also the,bow shape and the length of ship with same order of influence.
