Hydrodynamic effects of ship passage in confined channels: A multi-parameter study

Résumé

This study investigates the impact of inland navigation on inland. Two methods were used: experimental campaigns in the towing tank of the Pprime Institute and numerical simulations with the CFD software StarCCM+. These approaches allowed detailed analysis of the hydrodynamic effects caused by ship passage in confined channels. The experiments reproduced various navigation scenarios using adjustable banks. Flow velocities and surface elevations were measured with Stereo-PIV and stereo-refraction techniques. A numerical model was also developed using the SST k–ω turbulence model and mesh refinement near the free surface. It was validated against the experimental data. Four key parameters were studied: ship speed, initial water depth, channel width, and bank slope. Each had a strong influence on flow characteristics. Extreme conditions (high speed, shallow depth, narrow channels, and sloped banks) produced amplified effects. These included deeper surface depressions, stronger return currents, larger waves, more turbulent wakes, and sharper velocity gradients, especially near banks. This study highlights the need to control navigation conditions to protect riverbanks.
