摘要
海洋气象因子fw是国际海事组织(IMO)提出的EEDI计算公式中的重要成分,而船舶波浪增阻是决定fw的关键,由于国际上关于高速船波浪增阻预报方面的研究很不完善,为此文章基于二维半理论求解水动力和运动响应,利用几种不同方法对波浪增阻进行计算,并与模型试验结果相比较,在此基础上,推荐了一种适合计算高速船波浪增阻的方法。
The wave added resistance is one important part of ocean factor fw in EEDI formula presented by IMO. At presently the wave added restistance research on high speed ships is relatively few. In this paper, the hydrodynamic forces and ship motion response in waves are predicted by using 2.5D theory. On the ba-sis of ship motions, the waved added resitatnce is predicted by using several methods and compared with available model tests data. Based on comparisons, one numerical methods to predict wave added resistance on high speed ships is recommended.
