A time-domain potential-flow solver is developed to study the linearized ship- wave interaction problem. A Rankine panel method is implemented to model the case of a hull advancing in calm water and the problem of seakeeping with forward speed, yielding on the one hand the wave-making resistance and on the other the loads and motion responses in inci- dent waves. Meshes with multiple levels of refinement are used to improve the computational efficiency. Tests with impulsive waves are implemented for the seakeeping problem to reduce simulation times. The solver is validated on a Wigley hull for the calm water case, and on a Series 60 and a bulk carrier hull for the unsteady problem in head waves.

Abstract
A time-domain potential-flow solver is developed to study the linearized ship- wave interaction problem. A Rankine panel method is implemented to model the case of a hull advancing in calm water and the problem of seakeeping with forward speed, yielding on the one hand the wave-making resistance and on the other the loads and motion responses in inci- dent waves. Meshes with multiple levels of refinement are used to improve the computational efficiency. Tests with impulsive waves are implemented for the seakeeping problem to reduce simulation times. The solver is validated on a Wigley hull for the calm water case, and on a Series 60 and a bulk carrier hull for the unsteady problem in head waves.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
