摘要
为研究导流片对预制风管弯头气流组织的影响,通过选取了装饰工程中3种常用的大型弯头,并在其中设置不同形式的导流片,应用数值模拟的方式对不同形式的弯头和配置不同形式的导流片时,风管内的气流均匀性进行了研究。通过比较得出了3种大型弯头中导流片的布置对气流流动的影响,并结合风管系统内整体均匀性和出口风速得到了预制风管弯头的选型依据,以期为今后类似工程的风管弯头选型提供借鉴。
In order to study the influence of the deflector on the air distribution of the elbow of the prefabricated air duct, three kinds of commonly used large elbows in the decoration engineering are selected, and different deflectors are set in them. The air distribution uniformity in the air duct is studied by numerical simulation when different elbows and deflectors are configured. Through comparison, the influence of the arrangement of the deflector on the air flow in three kinds of large elbows is obtained, and the selection basis of prefabricated air duct elbows is obtained by combining the overall uniformity in the air duct system and the outlet wind speed, so as to provide reference for the selection of air duct elbows in similar projects in the future.
