| 中文摘要: |
| 为研究滑行艇的静水阻力性能，运用重叠网格技术，结合THINC/QQ界面捕捉格式及流体体积（VOF）插值算法，开发了高精度多相流固耦合求解器thincFoam/overset。利用此求解器，对Taunton系列滑行艇在不同体积弗劳德数条件下的静水阻力性能进行预测，并将预测结果与实际物理试验以及其他数值模拟结果进行了比较。研究结果显示，新开发的求解器能够准确地预测滑行艇从排水型转变为滑行航态过程中的动态载荷和运动姿态。当体积弗劳德数为7.12时，采用断阶设计的船底显示出明显优势，与传统设计相比，船体升沉幅值增加了21.7%，同时所受阻力降低了27.2%。研究为滑行艇的静水阻力性能预测提供了有效的数值工具，并深入探讨了船底断阶设计在提升阻力性能方面的作用。 |

| To investigate the calm water performance of planing hulls, an advanced multiphase fluid-structure interaction solver, termed thincFoam/overset, was developed. This solver integrates the overset grid method with the THINC/QQ interface-capturing scheme and a novel VOF interpolation algorithm. Using this tool, simulations were conducted on Taunton-series planing hulls under various volumetric Froude numbers. The predicted results were compared with experimental data and other numerical simulations. The findings indicate that the solver can reliably capture the dynamic loads and motion characteristics during the transition from displacement to planing modes. Notably, at a volumetric Froude number of 7.12, the stepped hull design showed clear advantages: heave increased by 21.7%, and resistance decreased by 27.2% compared to conventional designs. This study offers a practical numerical tool for predicting calm water performance of planing hulls and provides insight into the effectiveness of stepped hull designs in enhancing resistance . |
