The aim of the paper is to present a systematic study of an outboard engine for fast planning vessel. Two test cases have been considered; the first one consists of the pod operating in propelled and un-propelled configuration in a cavitation tunnel whereas the latter consists of the the isolated un-propelled pod advancing at constant speed in a free surface conditions. In both cases, several speeds have been considered (for the propelled case a suitable propeller model has been adoped) and the numerical results are compared with experiments carried out at the CNR-INSEAN cavitation tunnel and model basin #1 for the two set of simulations, respectively. Numerical computations have been performed with the unsteady Reynolds averaged Navier Stokes equation solver Xnavis.

Abstract
The aim of the paper is to present a systematic study of an outboard engine for fast planning vessel. Two test cases have been considered; the first one consists of the pod operating in propelled and un-propelled configuration in a cavitation tunnel whereas the latter consists of the the isolated un-propelled pod advancing at constant speed in a free surface conditions. In both cases, several speeds have been considered (for the propelled case a suitable propeller model has been adoped) and the numerical results are compared with experiments carried out at the CNR-INSEAN cavitation tunnel and model basin #1 for the two set of simulations, respectively. Numerical computations have been performed with the unsteady Reynolds averaged Navier Stokes equation solver Xnavis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
