Abstract:
The development of accurate modeling strategies for Reynolds averaged Navier-Stokes (RANS) or large-eddy simulation (LES) models for turbulent combustion is often severely impeded by the lack of reliable data. Recent advances in direct numerical simulation (DNS) of turbulent combustion make the analysis of DNS data a powerful tool in the development process of combustion models.
In this work, a systematic methodology of the development process will be discussed, which besides relying on experimental data makes use of the richness of DNS data. This methodology is then demonstrated using the example of model development for turbulent premixed flames close to the broken reaction zones regime.

Prof. Heinz Pitsch received his Ph.D. in mechanical engineering from RWTH Aachen University in 1998. He held post-doctoral positions at UC San Diego and Stanford University and joined the faculty of Stanford University in 2003. In 2010 he returned to RWTH Aachen University to assume his present position as the Director of the Institute for Combustion Technology. His main research interests are in the fields of combustion theory, combustion chemistry, turbulence, and multi-phase flows with application to technical combustion systems.
