Abstract

The Noise emitted by ships is one of the most important Noises in ocean and the propeller Noise is one of the major components of the ship Noise. Measuring the propeller Noise in laboratory despite the high accuracy and good reliability, costs a lot, has some complexities and is very time consuming. For this reason, the calculation of propeller Noise using numerical methods has been considered in recent years. In this study, the Noise of propeller in non-cavitating conditions is calculated by solving the Ffowcs Williams-Hawkings (FW-H) equations. A software for numerical calculation of propeller Noise, based on FW-H Equations, is developed and results are validated by experimental results. This study show that the results of the FW-H Noise code have also good agreement with experimental data.
