The prediction of the noise scattered by a submarine subject to the propeller tonal noise is
here addressed through a non-standard frequency-domain formulation that extends the use …

This paper presents two novel integral formulations for the prediction of sound scattered by
moving bodies, derived from the Lighthill and the Ffowcs Williams and Hawkings equations …

This paper presents a boundary-field integral formulation suitable for the prediction of noise
scattered by moving bodies. Although based on the same flow modeling assumptions, linear …

Acoustic and vortical disturbances in uniform mean flow bounded with solid surfaces are
investigated in this paper. A convective vector wave equation and a convection equation that …
