Challenge
Marine vessels, such as ships and submarines, have large structures that are excited by turbulent flows in the oceans. These structures generate high levels of underwater radiated noise (URN) at a frequency that interferes with the ability of marine species to communicate, hunt, migrate and echolocate. URN is a significant problem for the marine ecosystem, however the underlying noise generation mechanisms are complex and not yet fully understood.
Solution
The UTS Tech Lab team are developing mathematical models to predict and understand the hydroacoustic and vibroacoustic responses of marine vessels in turbulent flow. These models will enable the development of targeted noise mitigation strategies and reduce the environmental impact of research, fishing and military vessels.
