FIREPLUME

FIREPLUME project "Emergency numerical simulation of fire plumes, identification of sources to their dispersion" responds to the axis "Operational and technological responses". It offers the analysis and characterization of the source of the fire in terms of toxic emissions and the quantification of its impact. The main objective of the project is to provide scientific answers to operational and technological questions by developing a platform for predicting the consequences of an industrial fire and for emergency response, based on simulation. FIREPLUME project consists of three nested parts. The first part, entitled "Thermal degradation and production of pollutants", aims to study the rates of pollutant production as a function of the conditions associated with the fire. The experiments will be carried out on a small scale (CORIA, SPE and INERIS laboratories) and large-scale (INERIS) to obtain the emission rates at different scales in terms of qualification and quantification. The second part aims to define the source terms (LEMTA, CSTB, SPE). Finally, the work concerning the dispersion and dissemination of pollutants aims at coupling with the lower scale approaches developed in the previous task to simulate the evolution and the dispersion of the atmospheric plume resulting from combustion (SPE, INERIS). The experimental approach conducted in parallel will provide the initial conditions for the modeling tools as well as the computer code. The simulations will then be able to predict in near and far fields the dangerousness of the source and its dispersion in the air depending on the nature of the products used, the characteristics of the focus, and the data. In this way the deposition and fallout of the fire plume can be determined in the vicinity and the far field. This tool will be developed to be accessible to actors useful in crisis management (prevention or operation) caused by these major fires.
