摘要
基于STAR-CCM+,运用平均雷诺数方程和Realizable k-ε湍流模型,对一条宽船型、带有非流线型顶推装置的多功能工作艇的实船模型进行阻力性能预报,将计算的静水阻力与船模试验结果进行对比分析发现,计算值与实验值吻合良好,并给出了船体周围的流场信息。分析了多功能艇的特殊装置——顶推装置对船舶阻力的影响,发现在低航速时,顶推装置对于剩余阻力的影响较明显,为该船型的快速性优化提供了参考依据。
RANS equations and realizable k-ε turbulence model are used to predict the calm water resistance based on STAR-CCM+ for a multi-function vessel that has wide water plane and non-streamlined pushing installation.The calculation results agree well with the model experiment results.Information of the flow field around the hull is given.The pushing installation,the special equipment in the multi-function ship,has an influence on ship hull resistance.The residual resistance is larger with lower ship speed.It provides reference for further rapidity optimization of the ship type.
