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

该项目以世界上唯一的分层大气边界层模拟风洞之一为基础，将使用世界上最先进的一些仪器研究建筑环境中温度、湍流和迁移之间的复杂关系。迄今为止，在城市冠层内湍流和空气质量的研究中全面考虑温度影响的工作还很少。特别是，本项目旨在改进扩散和空气质量模式，为了更好地了解污染物当受到入射风和热浮力的影响时，（像汽车尾气一样）沿着街道峡谷分布。

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.
