Efficient prediction of flow-induced noise for marine vessels

点击翻译按钮获取中文摘要

This project aims to develop efficient and novel numerical methods in hydroacoustics for comparative studies of design modifications and operating conditions on noise generated by turbulent flow around marine vessels. Flow induced noise generated by marine vessels presents unique challenges for noise prediction methods which often results in vessels that do not meet their design specifications. The expected outcome is to provide efficient numerical capabilities that can play a role towards the design of quieter marine vessels to increase the stealth of Australia’s navy. This project will provide significant benefit to Australia’s maritime platforms and future submarine program. Environmental benefits include a reduction of anthropogenic underwater noise pollution from marine vessels, which is critical for the welfare of marine life.
