内河航运在物流运输中扮演重要的角色。本文以1艘96 TEU内河集装箱船为研究对象，采用雷诺平均纳维-斯托克斯（RANS）方法，对其实尺度下在2种不同断面航道下的水动力性能进行模拟和预报，并对阻力、船体绕流场、自由液面兴波及船体压力分布进行分析和对比，以揭示实尺度条件下2种航道断面形状对阻力、流场特性及压力变化的影响。结果表明，在航速6 km/h时，航道2中的集装箱船阻力在水深超过5 m后趋于稳定，船体周围流场与兴波变化较小，浅水效应明显减弱；在相同水深条件下，较窄的航道1航行阻力较高，且阻力变化更为敏感，尤其在水深较浅时，浅水效应更加显著。
Inland waterway shipping plays a crucial role in logistics transportation. This paper focuses on a 96TEU inland container ship, using the Reynolds-averaged Navier-Stokes (RANS) method to simulate and predict its hydrodynamic performance at full scale in two different cross-sectional channels. The study analyzes and compares resistance, local flow field, free surface wave generation, and pressure distribution to reveal the impact of channel cross-sectional shapes on resistance, flow field characteristics, and pressure changes under full-scale conditions. The results indicate that at 6 km/h, the resistance of the container ship in channel 2 stabilizes when the water depth exceeds 5 meters, with minimal changes in the surrounding flow field and wave generation, and a significant reduction in shallow water effects. Under the same water depth conditions, the narrower channel 1 exhibits higher resistance, with more sensitive changes in resistance, especially at shallow depths, where the shallow water effects are more pronounced.
