| Résumé | This paper presents an overview of the objectives, scope, research activities, outcomes, and brief discussions on the results of a recently completed 5-year collaborative project. The project developed a methodology based on numerical simulations and experimental tests. It implemented this methodology to predict non-cavitating propeller-induced noise and hull vibration and to characterise the propeller as the source of noise and vibration. The research team conducted experimental measurements to validate numerical calculations, including Finite Element (FE) and Computational Fluid Dynamics (CFD) simulations of scaled ship structural response, ship and propeller hydrodynamics, and propeller-induced URN. Procedures were developed to measure the propeller-induced shaft loads, hull pressures and underwater radiated noise at different propeller and ship configurations. Finally, employing the Design of Experiments, an engineering tool was developed to predict the onboard and far-field noise and onboard vibration parameters of a hull induced by the propeller(s) based on specific geometric and operational parameters of the hull and the propeller. The tools and procedures have enhanced the capabilities of the design and optimisation studies to minimise the propeller-induced noise and vibration while working in non-cavitating conditions. Further developments and validations of the numerical tools are recommended. |
