A potential flow model for linearized ship seakeeping in time domain is presented. The numerical algorithm is briefly described. The transient-test technique, based on the interaction of a mathematical wave packet with the advancing ship, is numerically simulated and allows to recover the efficiency of frequency-domain models. Solutions are presented for a frigate, a container ship and a mathematical tri-hull. A set of experiments, also of the transient type, has been performed to support the numerical findings.

Abstract
A potential flow model for linearized ship seakeeping in time domain is presented. The numerical algorithm is briefly described. The transient-test technique, based on the interaction of a mathematical wave packet with the advancing ship, is numerically simulated and allows to recover the efficiency of frequency-domain models. Solutions are presented for a frigate, a container ship and a mathematical tri-hull. A set of experiments, also of the transient type, has been performed to support the numerical findings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
