Abstract
  • The report describes the activity aiming to develop a computational model to predict hull-propeller interaction with emphasis on radiated noise and pressure fluctuations induced by non-cavitating and cavitating propellers. The computational methodology is based on a hybrid RANS/BEM model. Propeller flow calculations are performed through BEM, whereas the hull viscous flow is studied through a RANS model. Pressure fluctuations and radiated noise are evaluated by means of hydroacoustic models that are suitable to be coupled with hybrid RANS/BEM modelling of the hull-propeller configuration. In the report, theoretical and computational methodologies are briefly reviewed. Numerical applications are presented to assess the capability of proposed formulations to evaluate radiated noise and pressure fluctuations induced by propellers operating in the hull wake under non cavitating and cavitating conditions. Part of the material in the present report is included in \"VIRTUE\" Project Deliverable D4.3.10. (literal)
