Aims

Advanced study of the thermodynamical aspects and the numerical simulation of reacting flows with emphasis on combustion processes.

Main themes

Fundamentals of chemical reactions, thermodynamics of combustion.
Theoretical study of laminar flames and deflagrations.
Introduction to turbulent flames.
Introduction to detonations.
Numerical methods for the simulation of turbulent flames.
Numerical methods for the simulation of detonations and explosions.

Content and teaching methods

- The fundamentals: Thermodynamics of combustion. Chemical kinetics of combustion, velocity of an elementary reaction, chain reactions. Conservation equations for mass, momentum, and energy. Species diffusion and heat
conduction.

- Basics of flame modeling: diffusion flames, premixed flames. Turbulent flames and flame-turbulence interaction. The concept of flamelettes. The pdf approach for turbulent flame analysis. Analysis of detonations and explosions.
Two-phase reacting flows.

- Numerical methods: Direct Numerical Simulations (DNS) and its requirements. The approach of Reynolds-Averaged Navier-Stokes equations (RANS). Introduction to Large Eddy Simulation methods (LES). Analysis of the capabilities and limitations of each method via the study of specific cases selected from the literature.

- Other types of flows: Examples of extending the various numerical methods to other types of reacting flows (without combustion)

- Practical studies: Exercises related to Part 2, employment of a numerical method covered in Part 3 for a simple problem of a turbulent flame and/or discussion on recently published papers.


A significant part of this course is based on the research activities of the holder of the course. The detailed contents of this course may vary according to these activities.
