On the Theory of Hydrodynamical Forces Acting on a Two Dimensional Flat Ship Oscillating on a Water Surface

Abstract

A theory of a pulsating pressure distribution on a water surface of uniform flow is developed following Hanaoka's theory. They say this model simulates an oscillating gliding plank, but this may not be true because there exists no solution satisfying both Kutta's condition at trailing edge and the condition that a plank lies on a water surface. In this paper, a flat shallow-draft ship of them are treated in more detail. The principal aim is a mutual relation between the diffraction and radiation of wave. This knowledge, for example, solves directly a wave-energy absorption problem.
