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.

本项目旨在开发高效和新颖的水声数值方法，以比较研究船舶周围湍流产生的噪声的设计修改和操作条件。由船舶产生的流致噪声对噪声预测方法提出了独特的挑战，这通常导致船舶不符合其设计规范。预期的结果是提供高效的数字能力，可以在设计更安静的海洋舰艇方面发挥作用，以提高澳大利亚海军的隐身能力。该项目将为澳大利亚的海上平台和未来的潜艇计划提供重大利益。环境惠益包括减少海洋船舶造成的人为水下噪音污染，这对海洋生物的福祉至关重要。
