Ship motion in non-homogeneous media

Research output: Contribution to journalArticlepeer-review


This paper introduces some new aspects of flow non-homogeneity relevant to marine hydrodynamics, such as the influence of flow stratification, i.e. vertical gradients of both density and viscosity and their effects on the motion of surface and submerged vessels. Some problems involving ship motion are also studied, namely the full hydrodynamic problem of a body moving in a stratified medium and its interaction with the induced system of internal waves; the stability problem of a submarine crossing a thermocline; the motion of a submarine near viscoelastic movable seabed; and the maneuvering characteristics of landing crafts, river ferrous and slow ships moving over a soft-mud or silt covered bottom.
