The practical and rigorous solutions of the potential
problem associated with the harmonic oscillation of a submerged
rigid body of arbitrary shape is presented. The use
of Green's function reduces the determination of the potential
to the solution of an integral equation. The integral
equation is solved numerically and the dependency of the
hydrodynamic quantities such as added mass and damping
coefficients of the object on the frequency of the oscillation
is established.
Several checks are made on the numerical results. These
include the Haskind's relations check, an energy check for
the radiation problem, and comparisons with closed form
solutions. All the checks and comparisons are successful and
it appears that the numerical procedure employed yields valid
and accurate results.
