CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe propeller performances and in particular the non-stationary cavitating behaviour and its side effects, namely induced pressure pulses and radiated noise, are strongly dependent on the ship wake field. As a consequence, a correct prediction of the ship wake, considering the differences between model and full scale, is of utmost importance. In present study, results obtained by means of traditional and well established semi-empirical methods for wake scaling and direct RANS computations are compared, considering not only the differences in the wake field, but also their effect on the propeller non-stationary behavior, which is evaluated by means of a panel code. The results of the study allow to exploit the differences which may be expected by the designer using these different approaches.

| Abstract: | The propeller performances and in particular the non-stationary cavitating behaviour and its side effects, namely induced pressure pulses and radiated noise, are strongly dependent on the ship wake field. As a consequence, a correct prediction of the ship wake, considering the differences between model and full scale, is of utmost importance. In present study, results obtained by means of traditional and well established semi-empirical methods for wake scaling and direct RANS computations are compared, considering not only the differences in the wake field, but also their effect on the propeller non-stationary behavior, which is evaluated by means of a panel code. The results of the study allow to exploit the differences which may be expected by the designer using these different approaches. | |
