Numerical Simulation of the Squatting of Floating Bodies Moving in Shallow Water

In restricted waterways, ship operation is affected by the proximity of the boundaries such as the bottom, horizontal restrictions due to banks and quay walls. Numerical simulations of the ship behavior when moving in restricted water are proposed in the present paper based on a computational fluid dynamics (CFD hereafter) investigation technique. Comparisons with the corresponding numerical solutions for the unlimited water are provided to emphasize the effects of the water depths not only on the pressure distributions on the hull, but also on the sinkage, trim and overall hydrodynamic resistance.
