管道气流噪声是室内通风系统中的常见问题,由于后期改造十分困难,在设计阶段对管道内障碍物等因素产生的气流噪声进行准确预测计算是非常必要的。本文对该领域现有的主要分析方法和理论模型进行了回顾总结,并归纳其研究难点以及提出对未来工作的若干建议,以期有助于工程人员的设计工作以及本领域研究的进一步深化。
Pipeline airflow noise is a common problem in indoor ventilation systems. Due to the difficulty of subsequent reconstruction, it is necessary to accurately predict the airflow noise generated by obstacles in the pipeline during the design stage. In this paper, the main existing analysis methods and theoretical models in this field are reviewed and summarized, and their research difficulties are summarized and some suggestions for future work are put forward in order to contribute to the design work of engineers and further deepen the research in this field.
