基于AMESim和Fluent的载流管道系统降噪研究

Research on noise reduction in the pipe system based on AMESim and Fluent

针对某载流管路,采用AMESim和Fluent相结合进行仿真计算,对指定管路流噪声进行计算。设计出相应的低噪声水动力管系附件,并对管路加装导流降噪装置前后进行声学分析和评估。结果表明,该导流装置改善了管道相应位置的流动状态,对于相应的管路有较好的降噪效果。

This study is about a pipe. We combine the softwares of AMESim and Fluent to simulate, and calculate the flow noise of the specified pipe. Then we design the low noise hydrodynamic piping accessories, and analysis the acoustic pipe before and after the installation of noise reduction device. The evaluation result shows that the guiding device improves the current state of pipe noise reduction effect.
