Abstract

Flow and acoustics analyses have been carried out for an ice breaker ship. The numerical acoustic solution relies on the computational fluid dynamics simulations with regard to the sound generation. The numerical method for acoustics is based on a wave equation for the density perturbations which is solved using an acoustic finite element method. The simulations are compared to full-scale underwater noise measurements, as well as model-scale measurements conducted in a cavitation tunnel. The hydrodynamic performance of the thruster unit was well captured in the numerical simulations. The flow around the unit was visualized, and different hydrodynamic noise sources caused by the propulsion system were investigated. The hydrodynamic noise of the ship was decently captured in the simulations.

Funding

The authors would like to express their gratitude for the support granted by Business Finland (formerly, TEKES) within “PropNoise” project. Without the funding the research project could not have been realized. The authors wish to acknowledge VTT's HPC cluster (“The Doctor”) for computational resources. The authors also wish to express their gratitude to Arctia for providing the ice breaker Polaris for the underwater noise measurements. The authors are grateful to the Finnish Navy for assisting in the planning and execution of the noise measurements, and providing the Jurmo landing craft to carry out the measurements. The authors are very grateful for ABB for providing all the technical details of the propulsor units, which are the core matter in this study.
