Experimental investigation into effects of thermal buoyancy on flow and dispersion within an urban canopy layer

该项目以世界上仅有的模拟风洞的分层大气边界层之一为基础，将使用一些世界上最复杂的仪器来研究建筑环境中温度、湍流和交通之间的复杂关系。到目前为止，在城市冠层内的湍流和空气质量的研究中综合考虑温度的影响的工作还很少，特别是这个项目的目的是改进扩散和空气质量模型，以便更好地了解污染物(如汽车尾气)在入射风和热浮力的驱动下沿街道峡谷分布的机制。

This project, based in one of the world's only stratified atmospheric boundary layer simulating wind-tunnels, will study the complex relationships between temperature, turbulence and transport within the built environment using some of the world's most sophisticated instrumentation. To date, there has been very little work done to comprehensively include the effects of temperature in the study of turbulence and air quality within the urban canopy layer.In particular, this project is aimed at improving dispersion and air quality models, in order to better understand the mechanisms by which contaminants (like vehicle exhaust) distributes along street canyons when driven by both the incident wind and the effects of thermal buoyancy.
