First, LES must be adapted to complex geometries and for two-phase flows. Secondly, while most academic flames are unconfined flames where acoustics plays a limited role, real flames exhibit a much greater sensitivity to acoustic waves. Combustion instabilities are often encountered in industrial devices and can be analysed successfully using LES. However, acoustic tools, able to predict wave propagation and coupling with combustion, are needed to understand and control them.

The aim of the course is to present LES for gaseous and liquid flames. State-of-the-art CFD codes for acoustic analysis of unstable combustion will be presented and described. Lectures on experiments for two-phase flow combustion will be given to demonstrate the importance of these mechanisms in laboratory burners. Finally, an entire day will be devoted to discussions of unsteady combustion, LES and acoustic tools in industry. Industrial experts will comment on these tools.

The course is addressed to research experts from both academia and industry, to PhD and postdoctoral students. Basic knowledge in combustion science is recommended but not mandatory. Lectures will be given in English.
