摘要：

A source-to-far-field computation procedure aiming at predicting the noise generated by the underwater propeller was presented. Detached eddy simulation(DES) was used to resolve the unsteady flow field,which was taken as input data as noise propagation. Far-field sound radiation was performed by means of Ffowcs Williams-Hawkings(FW-H) equation. The computation procedure was finally applied to a typical marine propeller,David Taylor Model Basin(DTMB) 4118. The sound pressure and directivity patterns of this propeller were discussed.
