Dispersion characteristics of buoyant gases in urban areas

本项目涉及城市环境中浮力源（比空气轻或比空气重的气体）的释放和扩散。浮力源可能包括因事故或故意恶意释放的有害气体，以及热释放（例如从火中释放）。这项研究将主要是实验性的，将涉及使用EnFlo边界层风洞，这是NERC/NCAS和EPSRC/NWTF能够模拟中性或非中性大气流动的国家设施。目的是利用所获得的知识来发展或改进描述这些现象的模型。

This project is concerned with the release and dispersion of buoyant sources (gases that are either lighter-than-air or heavier-than-air) in urban environments. Buoyant sources can include hazardous gases, released because of accidents or maliciously on purpose, and thermally hot releases (e.g. from fire). The research will be mainly experimental and will involve the use of the EnFlo boundary-layer wind tunnel, a NERC/NCAS and EPSRC/NWTF national facility able to simulate either neutral or non-neutral atmospheric flows. The aim is to use the knowledge gained to develop, or improve, the models describing these phenomena.
