| 摘 要： | 近年来,全球气候变暖问题日趋严重,船舶的温室气体排放开始受到航运业的关注,新船能效设计指数( EEDI)并其来计算船舶的二氧化碳排放.主要研究近两年国际海事组织(IMO)海上环境保护委员会( MEPC)所关注的海洋气象因子fw.船舶的波浪增阻是计算影响因子fw时必需的一项重要参数.针对fn计算公式中船舶在零航速时波浪绕射增阻的计算方法进行研究,根据三维势流理论计算了简化船模、集装箱船及油船模型的波浪漂移力,并将计算得到的数值结果与日本专家提出的方法计算结果进行对比,发现了其中存在的一些问题并就这些问题做了分析和总结.目前fw的计算方法仍在研究中,研究成果对于该计算方法的完善有一定的参考价值.

| Abstract: | In recent years,global weather has become more and more warm and the greenhouse gas emissions from the ship began to be paid attention of the shipping industry.EEDI(Energy Efficiency Design index),which is a complicated formula to describe the ship's CO2(carbon dioxide) emissions.This study is mainly based on the MEPC(Marine Environment Protection Committee),which is a member of IMO(International Maritime Organization) and concerned about the effect coefficient due to sea condition(fw).While the ship's wave... |
