Abstract
A study of the first and second-order, dynamic, ideal
fluid effects on the forced, harmonic oscillations of a
rigid cylinder in a free surface is presented. The solutions
are obtained with a FORTRAN IV computer program based on the
finite element method using isoparametric elements.
First-order added mass and damping in heave for a semicircular
and bulb hull form including finite depth effects
are presented. Second-order solutions for the semi-circular
hull form in heave also including finite depth effects are
obtained. The solutions are verified by comparing with
existing theory and experiment.
