集装箱船机舱轴流风机噪声治理探讨

Noise Control of Axial-flow Fan in Engine Room of Container Ship

基于对轴流风机气动噪声产生机理的分析 ,讨论了风机性能和风道结构对噪声的影响及治理方案 ,同时对风机选型提出了建议。

Based on analysis of generation mechanism of flow noise produced by axial flow fan in the engine room of a container ship,the paper discusses the performance of the fan,the effects of the air piping structure on noise level and countermeasures,and proposes some recommendations for type selection of axial flow fan.
