本文总结了ASHRAE技术委员会（TC）4.3关于烟囱连接的研究结果。该研究的目的是量化排气管组合（即，相邻放置）的益处，以增加排气羽流的投掷或上升，从而减少不利的空气质量影响，而无需直接对排气管进行手动操作或使用诱导空气系统。该研究利用风洞模型开发了一个针对不同组合烟囱结构的羽流上升观测数据库。对羽流上升测量值进行分析，以根据组合烟囱的相对位置确定羽流上升增强系数。这项研究的结果可用于优化组合烟囱的布局，以便在所有风向下实现最大的羽流上升。 单位:双引文:ASHRAE交易，第114卷，pt。2008年1月1日，纽约

This paper summarizes the results of the research study conducted for the ASHRAE Technical Committee (TC) 4.3 on stack ganging. The purpose of the research was to quantify the benefits of ganging (i.e., placing next to one another) exhaust stacks to increase the throw or rise of exhaust plumes, thereby reducing adverse air quality impacts without directly manifolding the exhausts or using induced air systems. The research used wind tunnel modeling to develop a database of plume rise observations for various ganged stack configurations. The plume rise measurements were analyzed to determine a plume rise enhancement factor based on the relative positions of the ganged stacks. The results of this research can be used to optimize the layout of ganged stacks such that maximum plume rise can be achieved for all wind directions.Units: Dual
