摘要
波浪增阻的精确预报对船舶实际航行的性能分析具有重要意义。论文采用理论的和半经验方法,对集装箱船进行了规则波迎浪航行波浪增阻计算,与试验结果进行了比较,分析吃水和航速影响。理论方法基于水平线段移动脉动源的三维面元法求解速度势问题,进而采用三维船体辐射能量法得到船舶辐射增阻,基于二阶波浪力中绕射势得到绕射增阻;经验方法采用ISO15016-2015推荐的STAWAVE2方法。通过分析两种方法波浪增阻成分占比,得出了不同方法在不同频域段的适用范围。对半经验方法计算波浪增阻的关键参数进行了讨论,结合理论计算结果的趋势,针对集装箱船船型,提出了反映船型特征的预报波浪增阻的半经验方法。
In the paper,theoretical and semi-empirical methods are used for predicting added resistance of containerships advancing at constant speed and heading in regular waves.A comparative analysis is presented based on a comparison with experimental results,and effects of draught and speed are investigated.Potential problem is solved by the 3-D panel method based on translation of the horizontal line segment and the pulsating source panel.Added resistance due to radiation is obtained by 3D radiation energy method,while added resistance due to diffraction is obtained by the second order diffraction potential method STAWAVE2 recommended by ISO15016-2015.Key parameters of the semi-empirical method are discussed,and an improved semi-empirical method which can reflect characteristics of ship forms is presented.
