Abstract The resistance and ship-generated waves of two inland vessels in the fully-confined waterway are investigated based on numerical simulations. The simulation results are validated using towing tank experiments. The influences of the channel dimension, water depth, ship draught and velocity are studied. Specially, the ship resistance is characterized as a function of the blockage ratio and the theory of the linear ship wakes is corrected using the ship draught. These results are expected to predict the ship hydrodynamics in the restricted waterway and reveal the acting mechanism of the confinement effect on a certain level.

全封闭航道内河船舶阻力及波浪特征

摘要 基于数值模拟，研究了两艘内河船舶在全封闭航道内的阻力和船舶产生的波浪。模拟结果通过拖曳水箱实验得到验证。研究了航道尺寸、水深、船舶吃水和速度的影响。特别地，船舶阻力被表征为阻塞率的函数，并且使用船舶吃水校正线性船舶尾流理论。这些结果有望预测受限航道内的船舶水动力，并在一定程度上揭示约束效应的作用机制。
