With the constant increase of massively parallel computingpower, Large Eddy Simulation (LES) has emerged as a powerful numerical approach to address complex problems, such as turbulent reacting flows. LES is able to provide reliablepredictive solutions of both academic and real industrial systems, and gives new insight into the underlying physical phenomena. Moreover, to alleviate some uncertainty associated to boundary conditions, LES can be coupled to other solvers to include complementary system elements and physics in the computation.

After a rapid overview of the physical models,numerical methods and High Performance Computing (HPC) approaches used for LES, a selection of applications will be presented to demonstrate the capacity of LES and coupled multiphysics to tackle complex problems with accuracy and efficiency. 

 

Dr B. Cuenot obtained her engineering and master degree from Ecole Centrale de Paris in 1990. After one year as research engineer in the University of Boulder (CO, USA), she came back to France where she defended her PhD in 1995 and HdR in 2000, both in the field of numerical combustion. She is now the leader of the combustion research group at CERFACS, developping advanced softwares for the numerical simulation of turbulent combustion and heat transfer in industrial systems. Dr. Cuenot teaches combustion in various universities and has authored about 70 peer-reviewed journal papers. She is also much experienced in coordinating international projects, mainly financed by the European Commission where she also acts as an expert evaluator.
