短波顶浪中KVLCC2船模阻力增加CFD计算研究

波浪中航行船舶阻力增加，特别是短波中的阻力增加，是船舶界关注的焦点之一，也是船舶水动力学界研究的热点之一。论文采用基于RANSE的数值波浪水池技术，针对KVLCC2船型，开展了短波顶浪中船舶阻力增加的数值计算研究。与模型试验结果的比较表明，文中的CFD方法能够相当准确地计算短波顶浪中航行船舶的阻力增加；对船体各部分波浪增阻的分析表明，船体艏段产生的波浪增阻占主导地位，艉段的波浪增阻很小，而平行中体段对波浪增阻几乎无贡献。

CFD Computation of Added Resistance for KVLCC2 Model in Head Short Waves

Prediction of added resistance in waves is now a hot topic for ship performance in seaway, especially for the added resistance in short waves. In this paper, numerical computations of added resistance for KVLCC2 model advancing in regular head short waves were carried out by RANSE based on numerical wave tank technology. The computed results agree quite well with the experi-mental data, which means that the added resistance of ships heading in short waves can be comput-ed quite accurately by the CFD method in this paper. The computed results of added resistance at different parts of the ship hull show that the added resistance is primarily concentrated at the fore-segment, whereas the added resistance at the aft-segment is quite small, while the added resistance at the mid-segment can be neglected.
