Numerical study and acoustic analysis of propeller and hull surface vessel in self-propulsion mode

چکیده مقاله

In this article, the hydrodynamic analysis and noise of the propeller and the surface vessel hull were examined. The model selected in this study is a KRISO Container Ship (KCS) with a five-bladed propeller. Initially, the hydrodynamic analysis of the propeller in open water mode and then in self-propulsion mode was investigated using computational fluid dynamics. Simulations were carried out using a commercial solver, STAR-CCM+ (RANS equations with FVM and VOF model). Finally, the emitted noise from the propeller and the vessel hull was investigated using Fox William Hawkins equations. The pressure distribution and hydrodynamic performance (thrust, torque, efficiency) of the propeller in open water conditions and self-propulsion conditions, were achieved. Comparing the results of the hydrodynamic performance of the propeller in open water and self-propulsion modes with the experimental results indicates the acceptable results of the analyses.
