The numerical simulation obtained in Task N1.IN2 will be used for the estimation of far field noise radiated from the non-cavitating propeller in non-uniform (prescribed wake) inflow conditions. Induced noise will be analysed by means of both time history of pressure disturbance and spectral analysis of noise in a number of selected points in the far field. Simulations will also provide maps of the sound pressure level distribution in order to estimate the directivity features of the acoustic field.

Abstract
The numerical simulation obtained in Task N1.IN2 will be used for the estimation of far field noise radiated from the non-cavitating propeller in non-uniform (prescribed wake) inflow conditions. Induced noise will be analysed by means of both time history of pressure disturbance and spectral analysis of noise in a number of selected points in the far field. Simulations will also provide maps of the sound pressure level distribution in order to estimate the directivity features of the acoustic field.File in questo prodotto:
