The accidental or deliberate release of hazardous chemicals in urban
environments or industrial sites, potentially poses a substantial threat to the
environment and societies. It is crucial to be able to model, quickly
(e.g. quicker than ‘real-time’) and reliably, dispersion from localised sources
at short range (< 1 km, where the threat to human health is greatest) to inform
Large-Eddy Simulation (LES) is a high fidelity simulation tool that is able to
predict the instantaneous properties and behaviour of chemical releases in the
vicinity of complex geometries (e.g. from rural, semi-rural to urban
environments). Nevertheless, challenges remain, including (1) thermal
stratification effects due to global/localised surface heating, and (2) effects
of meteorological conditions on dispersion. This project will focus on (1) and
(2) for modelling gas dispersion, linking to other research activities at
Southampton where appropriate.
The primary goal of the project is to extend the capability (e.g. efficiency and
accuracy) of LES on such problems, and to provide a solid database (including
post-processed statistics data) for verification and extension of fast
