| When a ship enters a restricted shallow water area, the distance between the ship’s keel and the seabed decreases with the increase of speed, the ship’s sinking further increases, the longitudinal pitching motion becomes more obvious, and the ship itself is restricted in manoeuvring, which poses a great safety problem for the hull. Calm waters are selected as the experimental background, a rectangular canal model is established to simulate the actual restricted channel, and a standard container hull model is used to simulate and analyse the numerical values of ship sailing lifting and sinking through the commercial software STAR-CCM+ and Computational Fluid Dynamics methods, which show that: the simulation results match well with the values of physical experiments, and the growth of the ship’s sinking is directly proportional to the ship’s speed and the water holding; affected by the Under the influence of trim, the bow squat is always larger than the stern squat, and the growth of the stern squat is larger than the bow squat with the change of ship speed. This research result can provide theoretical support for the safe navigation of ships in restricted waters. |
