非对称双体船片体构型及阻力性能的数值研究

对于海上风电双体运维船而言,兴波阻力是其总阻力的重要组成部分.本文基于CFD技术对非对称双体船进行初步研究,通过改变双体船左右片体角度以及改变单侧片体肥瘦程度来实现内外片体排水体积差的目的2个方面来研究非对称双体船的阻力性能,比较各方案的阻力,综合考虑最终得出最优方案,为今后双体风电运维船的船型设计与优化提供一个新的研究方向.

Asymmetric catamaran hull configuration and the relevant research of resistance performance

For offshore wind power catamaran maintenance ship, wave resistance is an important part of the total resist-ance. In this paper, based on the CFD technology to a preliminary study of asymmetric catamaran, by changing the angle about catamaran hull and change one piece body lean degree to achieve the purpose of the drainage volume difference inside and outside of block two aspects to study the resistance, comparing the resistance of the programs, finally it is concluded that the optimal solution,which provide a new research direction for the future offshore wind power catamaran maintenance ship design and optimization.
