Research Interest

The main research interests of Denis Veynante focused on modeling and numerical simulations of turbulent reaction flows. He co-authored with Thierry Poinsot the textbook "Theoretical and Numerical Combustion". Current research activities are linked to the development of dynamic models to describe reaction rates in large eddy simulations (LES) of turbulent combustion. These models, pioneered by Germano et al. (1991) for momentum transport, take advantage of the known resolved flow scales to automatically adjust the sub-grid scale model parameters. They are currently successfully tested in turbulent jet flames, flame kernel developments and safety-related applications. Especially, model parameters do not require case-by-case adjustment anymore and are found to automatically vary when modifying operational conditions.

Another important topic is to take into account complex chemistry features in turbulent combustion models; These models are often developed assuming simple chemistries faster than turbulent time scales while chemical details are mandatory to describe flame stabilization mechanisms or pollutant formation, key ingredients for industrial applications and environmental requirements.

In collaboration with IFP-EN are also investigated 0D modeling of spark-ignited internal combustion engines, in view of system simulations, large-eddy-simulations of Diesel engine combustion and of ignition and flame kernel development in spark ignited engines.
