Objectives

The objective of this ERCOFTAC conference is to bring together experts in newly developed experimental and numerical techniques for tackling turbulent flames and featuring high resolution; typically high-speed diagnostics (planar laser simultaneous measurements PIV & PLIF) and high-resolution simulations (Direct Numerical Simulation-DNS or Large Eddy Simulation-LES with billions points and complex chemistry).  

Recent progress in computer architecture (massively parallel and high performance computing) renders it possible to envisage “routine” high fidelity simulations running on thousands of processors with billions of cells. As a first consequence, highly refined LES and even DNS of geometries similar the one encountered in industrial devices become feasible. The second consequence is that the current approaches of turbulent combustion modelling need to be revisited. Most of the target experiments that have been used in the past two decennia for the validation of the modelling approaches have been designed with simple geometries and relatively small Reynolds number, to accommodate the computing resources of that period. On the other side, experimental techniques have also enormously progressed (high speed cameras, simultaneous measurements of velocities and temperature with increased spatial and temporal resolution…) opening new possibilities for comparisons between simulation and experimental studies. New challenging well-documented experimental set-ups are now emerging to support and complement high-fidelity numerical simulations. 

This meeting will bring researchers from experimental and computational background together to share a very up-to-date state-of-the-art of both disciplines and pave the way for the next decade challenges in the context of turbulent combustion: advanced design assisted by simulation, prediction of pollutants, inclusion of multi-physics in the models (radiation, soot, spray…).

Tentative programme 

Four invited lectures, by experts in the field of turbulent combustion (two experimental and two computational), will be given, and participants will have the opportunity to present their work in contributed oral or poster presentations. These presentations will promote discussions between researchers using experimental techniques and researchers using LES or DNS to gain understanding in combustion.

Registration

There will be a modest registration fee for participants, reduced for ERCOFTAC members. There will be free participation for a number of young researchers.
