Research output: Journal article publicationJournal articleAcademic researchpeer-review


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。||Flow-generated noise is one of the common problems encountered in indoor ventilation system. It is necessary to accurately predict and calculate the flow-generated noise produced by in-duct elements at design stage, due to the difficulty to solving the problems after the commissioning of the system. This paper reviews existing major analytical methods and theoretical models in the field. The research difficulties are also discussed,together with suggestions for future work for the purpose of facilitating design efforts of engineers and further deepening researches in this field.
