EFFECT OF BODY PERTURBATIONS ON ADDED MASS- WITH APPLICATION TO NONLINEAR HEAVING OF SHIPS

摘要

A small perturbation theory is presented for determining the effect of a body perturbation on the elements of the hydrodynamic added mass tensor. The cardinal feature of the result is that the contribution to the added masses due to the perturbation is expressed directly in terms of the geometry of the perturbation and a pressure distribution oh the unperturbed body. By using the results of this theory approximate evaluation of added masses for many odd shapes can now be readily obtained.
