Editor: | Sánchez-Caja, Vladimir | Keywords: | Boundary element method; Propeller noise; Sheet cavitation; Ffowcs-Wiliams Hawkings; FWH | Issue Date: | Jun-2017 | Publisher: | VTT Technical Research Centre of Finland Ltd | Source: | International Symposium on Marine Propulsors (smp 2017) | Abstract (english): | The present article deals with the prediction of the underwater noise induced by ship propellers under consideration of sheet cavitation on the propeller blades. The calculation method is a hybrid approach combining a boundary element calculation method with the Ffowcs-Williams Hawkings equation. The method is applied to different simulation cases with increasing complexity. The final case considers the noise propagation in full-scale for a cavitating propeller in combination with a part of a ship stern. This simulation result is compared to a full-scale measurement. |
