能效设计指数(EEDI)的推出对船舶设计提出了更高要求。波浪增阻的快速预报在船舶型线设计中具有重要意义。本文提出一种混合的波浪增阻计算方法,结合经验公式和势流理论优势的同时规避了二者的缺点。在波长较长时,采用切片理论预报船体运动响应并使用Salvensen法对波浪增阻进行预报。在波长较短时,采用Faltinsen经验公式或者藤井和高桥的近似公式进行波浪增阻计算。引入一个过渡函数实现长短波中波浪增阻预报结果平稳过渡。对Wigley3、KVLCC2船和一艘50000 t油船在规则入射波下航行时的阻力增加进行数值计算,并与试验值和其他计算数据进行比较,验证了该方法的可靠性和适用性。
The energy efficiency design index (EEDI) puts forward higher requirements for ship design. Corresponding, the rapid prediction of added resistance in waves is of great significance. In this paper, a hybrid method for the calculation of added resistance in waves is proposed., which combines the advantages of the empirical formula and the potential flow theory while avoiding the disadvantages of both. For the long wave, STF method is adopted to predict the motion response of ships in waves and the added wave resistance is calculated by the Salvensen method. For short wave, empirical formula proposed by Faltinsen or Fujii and Takahashi is adopted. A transition function is introduced to realize the smooth transition between the added wave resistances in long wave and short wave wave. The added resistance of Wigley3、KVLCC2 and an oil tanker in waves are calculated and analyzed, and the corresponding numerical results agree well with experimental data. Thus, the reliability and applicability of the present method is verified.
