TitleLES for Scalar Dispersion - Towards a Fast Prediction Model
CategoryPhD Studentship
EmployerUniversity of Southampton
LocationUnited Kingdom, Southampton
InternationalYes, international applications are welcome
Closure DateSunday, October 11, 2015
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
decision making.  

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
prediction methods.

If you wish to discuss any details of the project informally, please contact Dr
Zheng-Tong Xie, Aerodynamics and Flight Mechanics research group, Email:, Tel: +44 (0) 23 8059 4493.

Funding information: the funding covers fees and stipend for an EU/UK student 
ONLY. The successful candidate will receive tax-free stipend 
£14,000-£15,000/year during the THREE years PhD study.

This project is run through participation in the EPSRC Centre for Doctoral
Training in Next Generation Computational Modelling (
