THE FORCED OSCILLATION OF SHALLOW DRAFT SHIPS

Abstract

Considering a three-dimensional disk with a circular or elliptic waterplane as a ship of shallow draft, the interaction between the disk oscillating with six degrees of freedom and the induced motion of the surrounding fluid is investigated. The potential problem is formulated by the use of the concept of surface distributed sources so that an integral equation for the source density is obtained. The numerical solution of the integral equation is found and the dependence of added mass, added moment of inertia, and damping factors on various frequencies is determined.
