Hydrodynamic Performance and Acoustic Response of Ship Propeller

The aim of the paper is to predict hydrodynamic performance and noise generated by propeller at different advance ratio speed propeller. Three bladed, DTMB 4119 model was created using NACA66 modified line, a = 0.8 hydrofoil profile. ANSYS Workbench software used for mesh generation computational analysis. A large-eddy simulation turbulence Ffowcs Williams-Hawkings (FWH) acoustic all simulations. moving reference frame simulate rotational effects 792 rpm, being 0.2 m, inlet velocity varied study effect ratio. transient analysis carried out time step value 0.0005 seconds total 0.6 seconds. parameters are validated comparing with experimental data available in literature. sound pressure level (SPL) plotted over frequency range 0 1000 Hz locations, speed, an 0.5, 0.7, 0.833, 0.9,1. structural, behaviour predicted two-way fluid structure interaction 0.833. major conclusions drawn from that values increased off-design conditions varying receiver locations. this useful designers carry further research order reduce
