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.
EnglishIn the present work, an analysis of a CP CLT propeller, functioning in stationary and non-stationary conditions, is presented. Results of model tests at the cavitation tunnel of the University of Genoa, in correspondence to different advance coefficients, cavitation number and inflow wake, are presented, and used in order to compare with numerical results obtained with different numerical approaches. In particular, an in-house potential Panel Code, a commercial RANSE solver (StarCCM+) and an open source RANSE code (OpenFoam) are employed for the analysis of steady and unsteady cavitation characteristics, allowing to clearly underline merits and shortcomings of the different numerical approaches. Particular attention is given to the complex phenomena related to the tip region where the influence of the endplate is more pronounced.
