Numerical simulation of Forest Fires, from combustion to emissions.

Workshop presentation

Friday, July 27th 2012

While it is well known that large wildland fires can create their "own weather", most numerical models devoted to large wildfire simulation neglected the feedback from the fire to the atmosphere. The availability of high performance computers and finer models opened the way for simulation to investigate coupled wildfire/atmospheric effects at different scales ranging from the flame to smoke dispersion across a continent.


The objective of the workshop is to present and exchange about the recent advances in wildfire combustion in a remote, stimulating and mind-lifting environment. Specific focus will be given to the different numerical approaches developed for the simulation of turbulent flame, fire front dynamics, fire emissions, atmospheric chemistry and model evaluation.
The week is divided in two parts:
  • The first three days host a small restricted workshop that holds the conclusion and of the IDEA project (« Incendies de forêts : simulation de la dynamique et des émissions atmosphériques par couplage de code », Forest Fires: propagation dynamics and atmospheric emissions simulation by code coupling) whose object was to create a reliable and integrated multi-scale approach for large-wildfire simulation. 
  • The last two days are open for contributions related to the development, use and validation of numerical tools in the field of forest fire science.
The last session will be devoted to present these advances to fire managers, in order to exchange with decision makers, which expect pragmatic answers. 
 
Selected and extended articles will be published in a special issue of « Natural Hazards and Earth System Sciences », an Open Access Journal of the European Geosciences Union.


 


Concept and Format
The provisional program of the conference is divided into four main topics representing the main scales involved in wildfire combustion:
  1. Combustion scale, solid to gaseous phase, combustion and associated atmospheric emissions.
  2. Flame scale, turbulent flame to fire burn experiments and analysis.
  3. Wildfire scale, large wildfire simulation, interaction with atmosphere dynamics 
  4. Atmospheric scale, chemistry, impact of the fire at the regional scale and model evaluation.
Authors are requested to send a short abstract relevant to one of these fields, possibly presenting recent advances or newly available simulation code, and must integrate an emphasis on its application in the wildfire community.
Results, methods and software will be presented on the last day in a meeting with wildfire decision makers, followed by discussions on future projects and objectives of the field.
 

Venue
The workshop will take place in Cargèse, a historical landmark on the sea-shore of the beautiful island of Corsica in the Mediterrenean sea, off the French and Italian coastlines.
It will be hosted in the Institute for Scientific Study of Cargèse (IESC), internationally recognized for the high quality of its scientific program.
