On May 9-12, 2005 a scientific workshop on Large Eddy Simulation and Acoustic Analysis Tools for Unsteady Combustion has been organized by CERFACS. This international event, hosted by Météo France in Toulouse, took place in the frame of the European Marie Curie Research project FLUISTCOM (Fluid-Structure Interaction for Combustion Systems) that is coordinated by CERFACS. This unique workshop has gathered leading European experts in the research field, attracting scientists from 9 countries (including the USA, Brazil and Australia). The industrial presence was very strong with engineers attending from SNECMA, Turbomeca, Alstom, Siemens PG, Rolls Royce, Pratt and Whitney, GDF, ENEL, etc.

High-level scientific courses and presentations were given by lecturers of CERFACS, research organisations and industry. The presentations essentially focused on various approaches to the numerical modeling of unsteady turbulence flow phenomena and acoustics encountered in combustion chambers. This research topic is motivated by the need for leaner combustion technologies and reduced emissions which can lead to the appearance of combustion instabilities in combustion systems.

During the 4-days course state-of-the-art CFD codes for acoustic analysis of unstable combustion were presented and described. Lectures were given on Large-Eddy Simulation as well as on gaseous and liquid two-phase flow combustion. The participation of nearly 100 researchers and engineers has confirmed the importance addressed to this high-technologic research domain.

A CD-Rom gathering all presentations will be freely distributed to the participants. People who did not attend the workshop can purchase the CD-Rom for a 50 € fee upon simple email request to labadens@cerfacs.fr
