Computation of the Velocity Potential for a Pulsating Source in a Fluid with Free Surface and Finite Depth.

Abstract

A technique is presented that allows the numerical evaluation of the velocity potential for a pulsating source in a fluid with a free surface and finite depth. The series expansion used to obtain a numerically tractable representation of the finite depth potential is in a form suitable for use with ship motion programs that employ source distribution techniques in conjunction with strip theory. The effects of water depth, source submergence, and pulsating frequency on the free-surface elevation are explored with the intent of demonstrating finite depth effects on readily identifiable physical parameter.
