THE WAVEMAKING OF A SHIP: APPROXIMATE SOLUTIONS BASED ON A PARAMETRIC FORMULATION

Two simple approximate solutions to the problem of the wavemaking of a ship in an inviscid fluid are presented. These approximate solutions are somewhat similar to those proposed previously by Guilloton, Wehausen, Dagan and Noblesse, but the present analysis leads to a new interpretation of the approximate solutions obtained in this paper. The analysis is based on a mapping of the actual flow region onto a parametric space bounded by the horizontal undisturbed free surface and a vertical cut on the ship centerplane. This parametric formulation is related to the approaches used by Guilloton, Wehausen, Dagan and Noblesse. The differences and similarities between these different approaches are discussed in detail, as well as the differences with the usual thin-ship theory.
