Combustion

Combustion is a phenomenon that transforms the chemical potential energy contained in the fuel into thermal energy. The objective of this course is to understand the phenomena of combustion. A particularly targeted point of application concerns aeronautical turbojets. We will see what are the essential kinetic mechanisms of combustion, we will try to understand the physics of premix and diffusion flames, and how to stabilize these flames. We will focus on the turbulent regimes of these flames. Then we will discuss the acoustics in the aeronautical chambers. We will also study the physics of combustion of sprays. The simulation in the aeronautical chambers is the final goal.
