In the absence of cavitation, underwater radiated noise from propellers and control surfaces can have significant contributions from a variety of sources, such as tip vortices, trailing edge noise and other fluid dynamic phenomena. Furthermore, the flow will, in general, cause the structure to vibrate inducing vibro-acoustic effects, such as propeller singing, that can be the dominant source of noise. If the structure is sufficiently flexible, steady deformations can also affect the flow field in a manner that changes the noise profile. The present work consists of numerical simulations of flow in non-cavitating conditions, evaluating the far-field noise using the acoustic analogy of Ffowcs Williams-Hawkings for arbitrary surfaces (Brentner and Farassat, 1998). As a simplification of the rotating propeller problem, we consider a foil based on a cross-section profile of a submarine-type propeller blade, mounted at the root on a wall. The aim is to isolate different sources of noise and investigate corresponding modelling strategies. In order to isolate sources of noise for a given configuration, we vary the turbulence model (URANS and LES) and the surface used to evaluate the source terms for the acoustic analogy.
