Abstract
The hydrodynamic forces and moments acting on a semi-displacement vessel with forward speed and drift angle are studied using linear potential theory and Rankine panel method and compared against experiments from INSEAN [1]. The flow is linearized using incoming flow velocity potential. The hollow in the free surface behind the transom stern is solved using the linear hollow model from authors [2]. It is shown that the performance of the present method in capturing the behavior of the forces is satisfactory and the cross-flow drag and free surface nonlinearities can to some degree be the sources of differences.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
