肥大型船舶实效伴流分析及预报

摘要

为进一步掌握肥大型散货船、油船实效伴流的变化规律并改善传统估算公式的实用性，基于对成因的内在分析，探讨部分影响实船实效伴流的主要参数，并总结出相应的规律。以近30艘实船的数据资料为依据，通过改良得到一种具备创新性、实用性、能反映实船实效伴流客观规律的预报方法。%In order to grasp the changing rule of full formed bulk and tanker′s effective wake fraction and improve the useful-ness of traditional estimation formula , some main affecting parameters are explored based on the inherent analysis of effective wake fraction′s cause.Meanwhile, nearly 30 real ships′datum are used to get a new and practical forecasting method which can reflect the objective law of effective wake fraction .
