| 中文摘要: |
| 以KCS集装箱标模和NACA翼型舵组成的船-舵系统为研究对象，通过求解RANS方程，对船-舵系统的舵力试验、纯横荡试验和纯艏摇试验进行数值模拟。基于计算得到的船-舵系统的水动力和力矩，通过曲线拟合确定对应的水动力导数。结合船-舵系统水动力参数、水动力导数以及回转性指数的数值计算结果，研究了不同舵翼型对船-舵系统回转性的影响。结果显示：船-舵系统水动力参数随舵剖面厚度的增大而减小。在小舵角（10°以内）下，船-舵系统水动力参数中纵向力受舵翼型影响并不显著，而横向力和转艏力矩出现了较为显著的差异；在大舵角（10°以上）下，3种力受翼舵型影响显著。作用在船后舵上的法向力随舵翼型厚度的增大而减小，增加翼型厚度会降低船舶回转性。 |

| This study investigates a ship-rudder system composed of the KCS container ship model and a rudder with NACA section. Rudder force tests, pure sway tests, and pure yaw tests are numerically simulated by solving the RANS equations. Hydrodynamic forces and moments acting on the ship-rudder system are computed, and corresponding hydrodynamic derivatives are obtained via curve fitting. Based on the predicted hydrodynamic quantities, hydrodynamic derivatives, and turning ability index, the effect of rudder section profile on the turning performance of the ship-rudder system is analyzed. Results show that hydrodynamic quantities decrease with the increase of the rudder sectional thickness. At small rudder angles (within 10°), the influence of the rudder profile on the hydrodynamic quantities of the ship-rudder system is not significant for the longitudinal force, while noticeable differences are observed in the lateral force and yaw moment. At large rudder angles (above 10°), all three forces are significantly influenced by the rudder profile. The normal force on the rudder decreases as sectional thickness increases, and the ship's turning performance deteriorates with larger rudder sectional thickness. |
