为探索多船编队航行减阻可行性,开展典型编队形式下的兴波阻力计算与分析研究。采用基于Dawson法的2阶面源法,对4艘Wigley船以单纵列、双纵列和“三体船”式编队等3种编队方式航行时的兴波阻力进行计算分析。通过对比分析可知,在Fn处于0.3~0.5区间,采取单列纵队可望得到较好减阻效果;在Fn处于0.45~0.65区间,采取“三体船”式编队可望得到较好减阻效果。在不同航速下,通过改变各船间的相对位置,可获得减阻效果。
The purpose of this paper is to explore the possibility of resistance reduction for multiple ships in given formations. Based on the Dawson method with second-order panel, the wave-making resistance of four Wigley-type ships in given formations are investigated. Three type of formations are provided, which are the single column, the double columns and the trimaran-type. When the Froude number is between 0.3 to 0.5, better resistance reduction will be achieved utilizing the single column formation. When the Froude number is between 0.45 to 0.6, the trimaran-type formation will provide better resistance reduction. For various velocities, the resistance reduction can be achieved with different formations.
