Abstract

The turning performance of a ship is an important aspect of its maneuverability, and accurately predicting the hydrodynamic forces during ship turning motion is of great significance for the safe maneuvering design of ships. This paper investigated the hydrodynamic performance of a KRISO container ship in steady turning using experimental and numerical approaches. The rotating arm tests were carried out in rotating arm basin of Zhejiang University, while the numerical simulations were conducted in commercial computational fluid dynamics software. Hydrodynamic forces and moments, hull surface wave height, wave patterns, and vorticity are studied under different velocities, radii, and drift angles. The results show that the increase in velocity has a significant impact on the forces and moments of the hull. The changes in longitudinal and transverse forces reflect the complex fluid dynamic interactions between the hull and water. Under conditions of small radius and large drift angle, the hull experiences greater forces and moments, indicating that stability and maneuverability will be more challenged during sudden turns. This study can provide experimental data and numerical simulation references for the research of ship turning maneuvers.

KCS船稳转水动力性能：实验与数值研究

船舶的转向性能是船舶操纵性的一个重要方面，准确预测船舶转向运动时的水动力对船舶的安全操纵设计具有重要意义。本文采用实验和数值方法研究了KRISO集装箱船在定常转弯时的水动力性能。旋臂试验在浙江大学旋臂池中进行，数值模拟在商业计算流体力学软件中进行。研究了不同航速、半径和漂移角下的水动力和力矩、船体表面波高、波浪型和涡度。结果表明，速度的增加对船体的力和力矩有显著的影响。纵向和横向力的变化反映了船体与水之间复杂的流体动力相互作用。在小半径和大漂移角条件下，船体承受的力和力矩更大，表明船体在急转弯时的稳定性和机动性将受到更大的挑战。该研究可为船舶转向操纵的研究提供实验数据和数值模拟参考。
