氨蒸气被释放到大气中，目的是测量羽流中的顺风浓度。通过实验改变三种氨蒸汽源特性——海拔高度、浓度和速度——来研究它们对顺风浓度的影响。测试的氨源特征如下:海拔2.0米（6.5英尺）和8.1米（26.5英尺），浓度100%和1%（按体积计），垂直速度10米/秒（32.8英尺/秒）和50米/秒（164英尺/秒）。氨蒸气探测器被放置在2.0米（6.5英尺）和8.1米（26.5英尺）的顺风高度为24米（80英尺）、48米（160英尺）和96米（320英尺）的地方。获得的数据库由81个版本组成。数据表明，随着海拔、浓度和上升速度的实验增加，地面氨蒸汽浓度分别降低了0.2、0.5和0.8倍。实验数据与羽流扩散模型的预测进行了比较。 单位:双引文:阿什雷交易，第107卷，第。1

Ammonia vapor was released into the atmosphere with the objective of measuring downwind concentrations in the plume. Three ammonia vapor source characteristics-- elevation, concentration, and velocity--were experimentally varied to investigate their influence on the downwind concentration. The tested ammonia source characteristics were as follows: elevations 2.0 m (6.5 ft) and 8.1 m (26.5 ft), concentrations 100% and 1% by volume, and vertical velocities 10 m/s (32.8 ft/s) and 50 m/s (164 ft/s). Ammonia vapor detectors were placed at 24 m (80 ft), 48 m (160 ft), and 96 m (320 ft) downwind at elevations of 2.0 m (6.5 ft) and 8.1 m (26.5 ft). The database obtained consists of 81 releases. The data indicate that ground-level ammonia vapor concentrations are reduced with the experimental increases in elevation, concentration, and upward velocity by factors of 0.2, 0.5, and 0.8, respectively. The experimental data are compared to predictions from a plume dispersion model.Units: Dual
