Shallow Water Ship Hydrodynamics

摘要

Equations for the shallow-water ship problem where a free surface plays an important role are derived. The steady flow around a slender ship is considered. The angle of attack of the undisturbed flow is small. This situation occurs quite often near shallow water harbor entrances or a ship maneuvering at shallow water where the variations in the course of the ship are with such a time scale that the flow may be considered to be stationary for each time interval. A coordinate system fixed to the ship, the positive x-axis is directed in the direction of the projection of the undisturbed incoming flow and the incoming flow makes an angle alpha with the x-axis is considered.
