Wind tunnel measurements of particulate matter concentration and wind speed to determine the deposition effect of urban green

This dataset contains measurements of particulate matter (PM) concentration and wind speed at the in- and outlet of a test section of an open-circuit wind tunnel to study PM deposition on urban green. The vegetation under study was the climber species Hedera Helix, which was grown against a screen in a planter. PM was introduced in the wind tunnel at the inlet bend (number 2 on the figure WT-design) and consisted of a mixture of Arizona fine test dust (dp > 0.3 µm) and soot (dp < 0.3 µm). The concentration measurements were performed with an optical particle sizer and a scanning mobility particle analyser. Wind speed was measured with a hot wire anemometer. Details of the files can be found in README.txt. This research was performed by the Sustainable Energy, Air and Water Technology (DuEL) group at the University of Antwerp (Belgium).

本数据集包含开环风洞试验段进出口处的颗粒物（Particulate Matter，PM）浓度与风速测量数据，用于研究城市绿地表面的颗粒物沉降行为。本次研究的植被为攀援植物常春藤（Hedera Helix），其种植于种植箱中并攀附于筛网之上。颗粒物从风洞入口弯管（对应WT-design图中的2号点位）引入风洞，其成分为粒径（dp）大于0.3微米的亚利桑那细测试粉尘与粒径（dp）小于0.3微米的炭黑混合物。颗粒物浓度测量采用光学粒子粒径谱仪与扫描迁移率粒子分析仪完成，风速测量使用热线风速仪。数据集文件的详细说明可参阅README.txt。本研究由比利时安特卫普大学可持续能源、空气与水技术（DuEL）研究团队开展。
