摘要
以肥大型散货船为研究对象,对其标称伴流进行数值模拟,研究船型特征对标称伴流的影响。通过已获得伴流试验数据的若干船型确定数值模拟策略,在此基础上对27条目标船型开展数值模拟研究,获得各船型的标称伴流。应用聚类分析算法,得到3个类别的伴流。建立线型特征的计算方法,用船舶尾部横剖面和水线面的线型特征分析伴流类别和伴流数值。研究结果表明,桨前水线面的组合形式对伴流的影响显著,回归分析可准确预报平均伴流值。
Taking full-formed bulk carriers as the research object,numerical simulations of nominal wakes are carried.Strategy is determined with the existing wake test data.Numerical simulations are carried out on 27 target ships,nominal wakes of which are obtained.A clustering analysis algorithm is applied to obtain three categories of wakes.A calculation method of the characteristics of the lines is established,and the wake category and wake value are analyzed according to the characteristics of the ship's stern cross sections and waterlines.The results show that the combination of the waterlines in front of the propeller has a significant effect on the wake.Regression analysis can accurately predict the average wake value.
