COFIN - Concentration Fluctuations

A project on concentration fluctuations in gas dispersion.
 

Concentration Fluctuations in Gas Releases by Industrial Accidents (COFIN)

EU-ENVIRONMENT programme, contract no. ENV4-CT97-0629 (1998-2000)

Random concentration fluctuations caused by atmospheric turbulence tend to intensify the hazards of toxic and flammable gas releases. Practical risk analysis of industrial hazards often involves dispersion modelling of the gas field. Unfortunately this usually does not include concentration fluctuations - existing theory is considered difficult in application or to rely on too idealised situations. Our objective is to develop a model framework applicable also for practical risk assessment. The approach will be semi-empirical, ie we shall examine the statistical properties of experimental data and include stochastic information in the models.
